    Mechanical exfoliation methods of two-dimensional materials have been an essential process for advanced devices and fundamental sciences. However, the exfoliation method usually generates various thick flakes, and a bunch of thick bulk flakes usually covers an entire substrate. Here, we developed a method to selectively isolate mono- to quadlayers of transition metal dichalcogenides (TMDCs) by sonication in organic solvents. The analysis reveals the importance of low interface energies between solvents and TMDCs, leading to the effective removal of bulk flakes under sonication. Importantly, a monolayer adjacent to bulk flakes shows cleavage at the interface, and the monolayer can be selectively isolated on the substrate. This approach can extend to preparing a monolayer device with crowded 17 electrode fingers surrounding the monolayer and for the measurement of electrostatic device performance.

    Abstract

    In this study, a physical reservoir computing system, a hardware-implemented neural network, was demonstrated using a piezoelectric MEMS resonator. The transient response of the resonator was used to incorporate short-term memory characteristics into the system, eliminating commonly used time-delayed feedback. In addition, the short-term memory characteristics were improved by introducing a delayed signal using a capacitance-resistor series circuit. A Pb(Zr,Ti)O<sub>3</sub>-based piezoelectric MEMS resonator with a resonance frequency of 193.2 Hz was employed as an actual node, and computational performance was evaluated using a virtual node method. Benchmark tests using random binary data indicated that the system exhibited short-term memory characteristics for two previous data and nonlinearity. To obtain this level of performance, the data bit period must be longer than the time constant of the transient response of the resonator. These outcomes suggest the feasibility of MEMS sensors with machine-learning capability.

    Vibration energy harvesters that use resonance phenomena exhibit a high output power density for constant frequency vibrations, but they suffer from a significant drop in performance for non-steady-state vibrations, which are important for practical applications. In this work, we demonstrate that the output power under an impulsive force can be increased significantly by placing a U-shaped metal component, called a dynamic magnifier (DM), under an MEMS piezoelectric vibration energy harvester (MEMS-pVEH) with a 6 mm long cantilever using a 3  μm thick Pb(Zr,Ti)O<sub>3</sub> film. Based on the results of numerical calculations using a model of pVEH with a two-degree-of-freedom (2DOF) system, the DM was designed to have the same resonant frequency as the MEMS-pVEH and a high mechanical quality factor ([Formula: see text]). The waveforms of the output voltage of the fabricated 2DOF-pVEHs were measured for impulsive forces with various duration times, and the output power was calculated by integrating the waveforms over time. The output power of the MEMS-pVEH placed on the DM with a [Formula: see text] of 56 showed a gradual change according to the duration of applying an impulsive force and a maximum of 19 nJ/G<sup>2</sup> (G: gravitational acceleration) when the duration of the impulsive force was 3.8 ms. This result was about 90 times greater than the output power of the MEMS-pVEH without a DM. While it is not easy to fabricate pVEHs with a complex 2DOF structure using only the MEMS process, we have demonstrated that the output power can be significantly improved by adding a spring structure to a simple MEMS-pVEH.

    The interface between conventional semiconductors and aqueous ionic solutions is an important target in chemistry and materials science. Recently, a wide variety of research has been done on transition-metal dichalcogenides (TMDCs) for use as 2D layered semiconductors, and their optoelectronic properties have been widely explored. One representative TMDC, monolayer (1L) MoS2, is known to show a photoluminescence (PL) signal of a direct band gap nature, and the PL intensity is dependent on the carrier concentration. Various methods of 1L MoS2carrier modulation have been shown to enhance the PL intensity in dry environments. In contrast, enhancement in an aqueous environment is limited, and a strategy to design an interface with aqueous media has not yet been established. One proposed idea was an aqueous acid interface; however, the enhancement of the PL with this method was usually minimal, about 1 order of magnitude. In this study, we demonstrate a method to achieve strong PL enhancement in 1L MoS2in an aqueous media by incorporating bis(trifluoromethane)sulfonyl anion (TFSI-ion) in an acidic environment. With the addition of the TFSI-ion in an acidic environment, the enhancement factor of the PL in 1L MoS2is more than 100 times greater than its PL intensity in water. The molecular anion is the key factor, as the TFSI-ion facilitates the oxidation of MoS2. This anionic effect is the additional factor needed to modulate the optoelectronic properties of 2D semiconductors in aqueous media. The proposed idea could have potential applications for biochemical sensors in aqueous situations.

    Carrier modulation in transition-metal dichalcogenides (TMDCs) is of importance for applying electronic devices to tune their transport properties and controlling phases, including metallic to superconductivity. Although the surface charge transfer doping method has shown a strong modulation ability of the electronic structures in TMDCs and a degenerately doped state has been proposed, the details of the electronic states have not been elucidated, and this transport behavior should show a considerable thickness dependence in TMDCs. In this study, we characterize the metallic transport behavior in the monolayer and multilayer MoS2 under surface charge transfer doping with a strong electron dopant, benzyl viologen (BV) molecules. The metallic behavior transforms to an insulative state under a negative gate voltage. Consequently, metal-insulator transition (MIT) was observed in both monolayer and multilayer MoS2 correlating with the critical conductivity of order e2/h. In the multilayer case, the BV molecules strongly modulated the topmost surface layer in the bulk MoS2; the transfer characteristics suggested a crossover from a heterogeneously doped state with a doped topmost layer to doping in the deep layers caused by the variation in the gate voltage. The findings of this work will be useful for understanding the device characteristics of thin-layered materials and for applying them to the controlling phases via carrier modulation.

    Graphene nanoribbon (GNR)-based materials are a promising device material because of their potential high carrier mobility and atomically thin structure. Various approaches have been reported for preparing the GNR-based materials, from bottom-up chemical synthetic procedures to top-down fabrication techniques using lithography of graphene. However, it is still difficult to prepare a large-scale GNR-based material. Here, we develop a procedure to prepare a large-scale GNR network using networked single-layer inorganic nanowires. Vanadium pentoxide (V2O5) nanowires were assembled on graphene with an interfacial layer of a cationic polymer via the electrostatic interaction. A large-scale nanowire network can be prepared on graphene and is stable enough for applying an oxygen plasma. Using plasma etching, a networked graphene structure can be generated. Removing the nanowires results in a networked flat structure whose both surface morphology and Raman spectrum indicate a GNR networked structure. The field-effect device indicates the semiconducting character of the GNR networked structure. This work would be useful for fabricating a large-scale GNR-based material as a platform for GNR junctions for physics and electronic circuits.

    Ferroelectric HfO2-based thin films, which have been attracting a great deal attention because of their potential use in various applications, are known for their unique properties, such as a large time-dependent imprint and wake-up effect, which differentiate them from conventional ferroelectric materials. In this study, direct piezoelectric measurement was employed to investigate the state of polarization during the retention and wake-up process without applying an electric field. The polarization-electric field hysteresis loop of a sputtered Hf0.5Zr0.5O2 (HZO) film with a thickness of 10 nm showed a time-dependent imprint at room temperature during polarization retention, and the internal electric field that generated the imprint gradually increased from 0.05 to 0.6 MV/cm. While a space charge density of more than 1 μC/cm2 is required to form such an internal electric field, it was found that the magnitude of the direct piezoelectric response did not change at all during polarization retention. On the other hand, both the remanent polarization and direct piezoelectric response increased during the wake-up process. Based on the difference in the variation over time of these two characteristics, we concluded that the non-ferroelectric layer exists at the interface between the HZO film and TaN electrode and gradually transitions to ferroelectric phases through the electric field cycle.

    The electron excitation mechanism and the spin accompanied by electron transition in a multiferroic YMnO3 epitaxial thin film were studied using photoluminescence (PL) spectroscopy. The thin film exhibits an intra-atomic transition of Mn3+ and the A1 optical coherent phonon. This study particularly focuses on the correlation between the electron transition corresponding to the on-site Coulomb energy and antiferromagnetic spin order. To clarify the complex excitation mechanism, the excitation energy and temperature dependences of the PL were analyzed. The key finding was that the intensities of the PL band at 1.43 eV increase as the excitation energy approaches the absorption peak energy corresponding to the on-site Coulomb energy and as the temperature decreases below 80 K, corresponding to the Néel temperature. These results suggest that the PL band is mediated by the spin-flip and relaxation processes.

    The discovery of the HfO2-based ferroelectric films has opened new opportunities for using this silicon-compatible ferroelectric material to realize low-power logic circuits and high-density non-volatile memories. The functional performances of ferroelectrics are intimately related to their dynamic response to external stimuli, such as electric fields at finite temperatures. In the case of HfO2-based films, the time-dependent imprint and wake-up effect, which distinguish them from conventional ferroelectrics, play important roles in understanding the remaining reliability issues, such as insufficient endurance. In this study, the time-dependent imprint process is carefully investigated using Hf0.5Zr0.5O2 (HZO) films with different ferroelectric properties and defect density. The amount of redistributed charge, which causes imprint during polarization retention, is affected by the remanent polarization of the ferroelectric layer, suggesting that the depolarization field corresponding to the remanent polarization generates and works as a driving force of charge redistribution. The time-dependent measurement of the imprint distinguishes the origins of charge redistribution processes, which have different time constants. In addition, the correlation between the amount of redistributed charge and the dielectric relaxation of the HZO films is discussed. Correlations are identified between the redistributed charge and the dielectric relaxation, indicating that the mobile charge contributes to the time-dependent imprint.

Monolayer transition metal dichalcogenides (TMDCs) have received significant attention as direct band gap semiconductors and a platform for optical applications and physics. However, bilayer or thicker layered samples exhibit an indirect band gap. Here, we propose a method that converts the indirect band gap nature of bilayer MoS2, one of the representative TMDCs, to a direct band gap nature and enhances the photoluminescence (PL) intensity of bilayer MoS2 dramatically. The procedure combines UV irradiation with superacid molecular treatment on bilayer MoS2. UV irradiation induces the conversion of the PL property with an indirect band gap to a direct band gap situation in bilayer MoS2 when the interaction between the top and bottom layers is weakened by a sort of misalignment between them. Furthermore, the additional post-superacid treatment dramatically enhances the PL intensity of bilayer MoS2 by a factor of 700×. However, this procedure is not effective for a conventional bilayer sample, which shows no PL enhancement. From these results, the separated top layer would show a strong PL from the superacid treatment. The monolayer-like top layer is physically separated from the substrate by the intermediate bottom MoS2 layer, and this situation would be preferable for achieving a strong PL intensity. This finding will be useful for controlling the optoelectronic properties of thick TMDCs and the demonstration of high-performance optoelectronic devices.

    For a comprehensive study of the growth mechanisms of Pb(Zr,Ti)O3 (PZT), we employed a combinatorial sputtering method that enabled us to fabricate films with composition and substrate temperature gradients in-plane. The gradient of the amount of Pb supply was created using PZT ceramic and Pb3O4 powder targets. The substrate temperature gradient was generated in an orthogonal direction by inserting a shadow mask between the heater and substrate. The PZT film was deposited on uniformly deposited (001)LaNiO3/Si in a substrate temperature range of 490 °C-570 °C. It was determined that although the growth condition of PZT films has a relatively large process window, the orientation is easily changed by the temperature and the amount of Pb supply. In addition, the range of the growth temperature, where the films show ferroelectricity decreases with decreasing the amount of Pb supply.

    © 2020 The Japan Society of Applied Physics. This study investigated the electromechanical properties of MEMS piezoelectric vibration energy harvesters (MEMs-pVEHs) under various impulsive forces to discuss effective harvesting energy from random vibrations. MEMS-pVEHs with different resonance frequencies with an energy conversion efficiency close to the theoretical maximum were used. The output waveforms for various impulsive force could be fitted well with the dynamic model of pVEHs. The output energy density reached 34 nJ g-1 for an impulsive force with an acceleration of 8 m s-2. To obtain high energy conversion efficiency, pVEHs should have a response time longer than the duration of the impulsive force; efficiency higher than 50% was obtained by an impulsive force with a short duration. Furthermore, the study investigated the pVEH requirements for impulsive force based on the results of numerical simulation.

    © 2020 The Japan Society of Applied Physics. A new type of ferroelectricity, originating from charge order and coupled to magnetism, occurs in YbFe2O4 containing triangular Fe/O double layers, which has recently generated great interest in this material. YbFe2O4 tolerates more than 10% iron deficiency even in bulk single crystals with space group R3m. Even though a large number of Fe deficiencies are introduced in the thin film form due to vaporization of Fe ions during deposition at high temperatures, the crystal structure with the space group of R3m in the films never changes within the Fe/Yb composition ratio from 1.3 to 2.2. In the previous research, the effects of the Fe/Yb composition ratio - especially in the large Fe deficient area (1.31-1.86) - on the lattice distortion and chemical bonding state of non-stoichiometric (0001)-oriented YbFe2O4 epitaxial thin films on (111) YSZ and (0001) sapphire substrates were examined. The variation of the lattice constant, Raman spectra, and optical absorption coefficient indicated that the existence of the stacking fault and the antisite Yb play an important role in the significant iron deficiency without changing the crystal structure of non-stoichiometric YbFe2O4 thin films.

    © 2020 American Chemical Society. To advance the development of atomically thin optoelectronics using two-dimensional (2D) materials, engineering strong luminescence with a physicochemical basis is crucial. Semiconducting monolayer transition-metal dichalcogenides (TMDCs) are candidates for this, but their quantum yield (QY) is known to be poor. Recently, a molecular superacid treatment of bis(trifluoromethane)sulfonimide (TFSI) generated unambiguously bright monolayer TMDCs and a high QY. However, this method is highly dependent on the processing conditions and therefore has not been generalized. Here, we shed light on environmental factors to activate the photoluminescence (PL) intensity of the TFSI-treated monolayer MoS2, with a factor of more than 2 orders of magnitude greater than the original by photoactivation. The method is useful for both mechanically exfoliated and chemically deposited samples. The existence of photoirradiation larger than the band gap demonstrates enhancement of the PL of MoS2; on the other hand, activation by thermal annealing, as demonstrated in the previous report, is less effective for enhancing the PL intensity. The photoactivated monolayer MoS2 shows a long lifetime of ∼1.35 ns, more than a 30-fold improvement over the original as exfoliated. The consistent realization of the bright monolayer MoS2 reveals that air exposure is an essential factor in the process. TFSI treatment in a N2 environment was not effective for achieving a strong PL, even after the photoactivation. These findings can serve as a basis for engineering the bright atomically thin materials for 2D optoelectronics.

    © 2020 The Japan Society of Applied Physics. The electrocaloric (EC) effect of ferroelectric polymer film was investigated at a high frequency. The analysis used the finite element method and revealed that the extractive heat density per unit of time increases and the thermal diffusion length decreases with an increase in the frequency of the driving electric field. Given the small thermal diffusion coefficient of ferroelectric polymers, the high-frequency drive of the EC effect for ferroelectric polymer film is promising for cooling devices. To discuss the EC effect under an alternating current (AC) electric field, the EC temperature change of the vinylidene fluoride-trifluoroethylene copolymer 75/25 P(VDF-TrFE) film with a thickness of 2 μm was characterized through direct measurement using a thin-film thermocouple. The EC temperature change increases with an increase in the electric field and frequency and reached up to 0.23 °C at 1.5 MV cm-1 and 10 kHz. The extractive heat density was estimated to be as high as 0.69 W cm-2

    © Published under licence by IOP Publishing Ltd. The output characteristics of MEMS piezoelectric vibration energy harvesters (PVEHs) under random oscillations are analysed. We fabricated cantilever-type MEMS-PVEHs using Pb(Zr,Ti)O3 films. The autocorrelation function of the transient displacement of the cantilever tip under random oscillations features a narrow-band random vibration. From the power spectral density (PSD) of the output voltage of the PVEHs, the resonance frequency decreases and the full-width at half-maximum increases with increasing vibration acceleration. By comparing output properties under various sinusoidal oscillations, nonlinear effects including the soft-spring effect and nonlinear damping effect clearly influence the output characteristics under random oscillations. The power generation is proportional to the square of the vibration acceleration even in the acceleration region where nonlinear effects become conspicuous.

    © 2019, The Author(s). Polarisation domain structure is a microstructure specific to ferroelectrics and plays a role in their various fascinating characteristics. The piezoelectric properties of ferroelectrics are influenced by the domain wall contribution. This study provides a direct observation of the contribution of domain walls to the direct piezoelectric response of bismuth ferrite (BiFeO3) films, which have been widely studied as lead-free piezoelectrics. To achieve this purpose, we developed a scanning probe microscopy-based measurement technique, termed direct piezoelectric response microscopy (DPRM), to observe the domain structure of BiFeO3 films via the direct piezoelectric response. Quantitative analysis of the direct piezoelectric response obtained by DPRM, detailed analysis of the domain structure by conventional piezoelectric force microscopy, and microscopic characterisation of the direct piezoelectric properties of BiFeO3 films with different domain structures revealed that their direct piezoelectric response is enhanced by the walls between the domains of spontaneous polarisation in the same out-of-plane direction.

    © 2019 The Japan Society of Applied Physics. To investigate the effects of small amounts of oxygen on the crystal growth process and structural changes in HfO2-based films, film was deposited on a Si substrate using HfO2 and ZrO2 targets via RF magnetron co-sputtering with small amounts of added O2. Even when the deposition was carried out without heating, the most stable monoclinic phase mainly formed at O2 partial pressures above 1 mPa, where the sputtering maintained the oxide mode in the as-deposited state. With decreasing O2 partial pressure, the amorphous component increased. During the annealing process, the metastable tetragonal or orthorhombic phase crystallized when the amorphous film was deposited at a lower O2 partial pressure of 1 mPa. The volume fraction of the metastable phase decreased abruptly at an O2 partial pressure at which the sputtering mode changed from metal mode to oxide mode. These results indicate that the O2 partial pressure during deposition have an effect on the crystal growth process and causes structural changes in the film even after the annealing process.

    © 2019 The Japan Society of Applied Physics. The magnetic field surrounding an AC current-carrying wire is a promising source for energy harvesting. In this study, an AC magnetic field energy harvester is developed based on the piezoelectric vibration energy harvester. A permanent magnet placed near the AC current-carrying wire vibrates by coupling with the AC magnetic field. The kinetic energy of the vibration can be converted by the piezoelectric effect. Theoretical analysis indicates that the harvester composed of a piezoelectric cantilever with a permanent magnet at the free end should be placed so that the magnet and the wire do not collide. Then, the harvester was fabricated using a piezoelectric bimorph cantilever with a mechanical quality factor of 66 and a generalized electromechanical coupling factor (K 2) of 3.1% and a neodymium magnet with a mass of 3.1 g. At an AC current of 5 Arms with a frequency of 50 Hz, an output of 1.3 mW was obtained.

    © 2019 The Japan Society of Applied Physics. The crystal growth of YbFe2O4 requires oxidant-poor conditions, thus YbFe2O4 usually contains a large number of iron deficiencies even in the bulk single crystal. The use of an ArF laser for laser ablation is effective to reduce the amount of active oxygen species and a wide process window to form the YbFe2O4 epitaxial films becomes available. By using the widened process window and an iron-rich target, the chemical composition of the YbFe2O4 epitaxial thin films is successfully controlled. The effect of the iron composition on the charge ordering transition can be discussed using the nonlinear I-V behavior. The threshold electric field changes depending on the iron composition owing to the broadening of the 3-dimensional (3D) charge order region, which affects the robustness of the 3D charge order against an electric field in YbFe2O4 thin films.

    © 2019 The Authors. Published by Wiley-VCH Verlag GmbH & Co. KGaA. Transition metal dichalcogenides (TMDCs) have received attention as atomically thin post-silicon semiconducting materials. Tuning the carrier concentrations of the TMDCs is important, but their thin structure requires a non-destructive modulation method. Recently, a surface-charge transfer doping method was developed based on contacting molecules on TMDCs, and the method succeeded in achieving a large modulation of the electronic structures. The successful dopant is a neutral benzyl viologen (BV0); however, the problem remains of how to effectively prepare the BV0 molecules. A reduction process with NaBH4 in water has been proposed as a preparation method, but the NaBH4 simultaneously reacts vigorously with the water. Here, a simple method is developed, in which the reaction vial is placed on a hotplate and a fragment of air-stable metal is used instead of NaBH4 to prepare the BV0 dopant molecules. The prepared BV0 molecules show a strong doping ability in terms of achieving a degenerate situation of a TMDC, MoS2. A key finding in this preparation method is that a convection flow in the vial effectively transports the produced BV0 to a collection solvent. This method is simple and safe and facilitates the tuning of the optoelectronic properties of nanomaterials by the easily-handled dopant molecules.

The present study reports the improvement of piezoelectric properties of sputtered BiFeO 3 films, and application to piezoelectric MEMS vibration energy harvesters (MEME-pVEHs). (100)-oriented BiFeO 3 films were obtained on (100)-oriented LaNiO 3 bottom electrodes grown on (100) Si substrates at deposition temperatures ranging from 450 °C to 550 °C. While all the films showed well-defined ferroelectric hysteresis loops at room temperature, the highest e 31,f coefficient of −3.6 C/m 2 was obtained at 500 °C. The increase of the e 31,f coefficient with increasing of the Rayleigh constant indicates the domain wall substantially contributes to the piezoelectric properties of the BiFeO 3 films. MEMS-pVEHs measuring 1 × 6 mm 2 and Si proof mass of 3.0 mg were fabricated using the BiFeO 3 film. The resonance frequency, electromechanical coupling factor, and mechanical quality factor were determined as 151.2 Hz, 0.1%, and 850, respectively. The maximum output power was 2.4 μW at 0.3 G, which is comparable with that of the best-performing MEMS-pVEHs using Pb(Zr,Ti)O 3 films.

However, an issue is its low luminescence brightness. In this research, we demonstrate a strategy to achieve strong photoluminescence (PL) of monolayer MoS2, by treatment with a redox-active molecule, fluoranil. An important finding is that the factor of PL enhancement depends strongly on the solvent used and the PL changes by more than one order of magnitude. This work is useful for harnessing the strong optical properties of MoS2 by the combination of oxidizing molecules and engineering the solvent used.

    © 2019 American Chemical Society. Modulating the electronic structure of semiconducting materials is critical to developing high-performance electronic and optical devices. Transition metal dichalcogenides (TMDCs) are atomically thin semiconducting materials. However, before they can be used successfully in electronic and optical devices, modulation of their carrier concentration at the nanometer scale must be achieved. Molecular doping has been successful in modulating the carrier concentration; however, the scientific approach for selective and local carrier doping at the nanometer scale is still missing. Here, we demonstrate a proof-of-concept of modulating the carrier concentration of TMDCs laterally on a scale of around 100 nm using spontaneous pattern formation of an ultrathin film consisting of molecular electron dopants. When the water made contact with the molecular film (∼10 nm), a spontaneous pattern formation was observed on both the monolayer and bulk TMDCs. We revealed that the pattern-formation dynamics and nanoscopic flow rate of the molecules were highly dependent on the thickness of the TMDCs, since the band gap varies based on the number of layers. Analyses of topographic images of the molecular patterns and photoluminescence spectra of the TMDCs indicated that the spontaneously patterned molecular films induced a local carrier doping. Our results demonstrate a spontaneous formation of a mosaic electronic structure. This work is useful for making tiny-scale electronic junctions on TMDCs and semiconducting materials to make numerous p/n junctions simultaneously for optoelectronic devices.

    © 2019 Author(s). Enhancing the output power at small input acceleration is a major concern for enabling practical application of vibration energy harvesters. In this study, a two-degree of freedom system (2-DOF) was employed to solve this issue. The numerical calculations using the lumped parameter model of the piezoelectric vibration energy harvesters (pVEHs) with 2-DOF indicate that the harvesters show two resonance peak and an increase in the output power of several ten times compared with the harvester with a single degree of freedom. Based on calculations, the prototype of pVEH with 2-DOF was fabricated using a micro-machined pVEH and a metal cantilever. The output power of the harvester is 3.4 μW at 0.1 Grms, which is 17 times higher than that of the micro-electro-mechanical system-pVEH. Moreover, the resonance frequency on the pVEH with 2-DOF is easily adjusted because of the coupled vibration of the two masses.

KGaA, Weinheim Recently, BaSnO 3 has attracted great attention as a promising transparent oxide semiconductor with a large bandgap (3.3 eV) and high mobility (320 cm 2 V −1 s −1 ), and many reports have discussed the origin of its high mobility. Specifically, its effective mass m* has been investigated with both calculations and experiments. First-principles calculations have suggested that m* is small near the Γ point and that this m* assists the high mobility. Therefore, it is quite important to study the anisotropy in the mobility of this material. However, except for (001) BaSnO 3 , there are almost no reports on the electrical transport properties of the films with other orientations. In this paper, the authors fabricate (111) and (001) (Ba,La)SnO 3 films by using pulsed laser deposition to evaluate the structural differences including the epitaxial strain and the orientation distribution generated from the differences in the growth mode that is originated in the ionic arrangement of each surface. The effects of the structural differences for the conductivities of (001) and (111) films and how do the authors achieve the epitaxial films with high mobility are discussed.

    © 2019, The Korean Physical Society. BiFeO 3 (BFO) ceramics were prepared by conventional solid-state reaction method without quenching. The effect of the sintering condition on the phase evolution and the ferroelectric properties of these BFO ceramics were investigated. A pinched polarization - electric field (P-E) hysteresis loop was observed in the sample sintered at high temperature for a short period (820 °C for 1 hour) because the domain wall motion is restricted by a large number of ionic defects such as oxygen vacancies. The BFO sample sintered at low temperature for a long period (760 °C for 6 hours) displayed a well-saturated P-E hysteresis loop due to its low ionic defect density.

    © 2019 Author(s). Recently, a number of papers have demonstrated sub-60 mV/decade switching by using the negative capacitance (NC) effect in ferroelectric-gate FETs. However, the physical picture is not yet understood. In this paper, an alternative physical picture for emerging NC is proposed and the development of the NC stage at the ferroelectric/semiconductor hetero-junction is described. Proposed physical picture is based on two factors, 1. "decrease in an additional voltage originated from the depolarization field by surface potential of semiconductor" and 2. "Change in the distribution ratio of gate voltage (V G ) to voltage applied to the ferroelectric layer (V F ) and surface potential of the semiconductor (ψ S ) due to the capacitance change of semiconductor." With considering these two essential phenomena, time-resolved simulations of the NC stage emerging at the ferroelectric/semiconductor hetero-junction were carried out. This NC phenomena expressed by the negative differential of the D F for the V F , i.e. (D F /V F <0), emerging in the MFS (metal/ferroelectric/semiconductor) capacitor without inserting dielectric layer, are dynamically simulated to discuss the proposed NC process. The simulation results clearly reveal that the NC stage is originated from the existence of additional voltage caused by the depolarization field by surface potential of semiconductor originated from the existence of remanent polarization of ferroelectric layer, and change in the capacitance of the semiconductor during polarization switching. The different physical picture from steady-state NC and transient NC can be clearly shown.
