    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.

    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.

    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.

    © 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, Springer Nature Singapore Pte Ltd. Controlled-polarization-type ferroelectric-gate thin film transistors (FeTFTs), which utilize the interaction between the polarizations of a polar semiconductor and a ferroelectric layer, have been proposed. When the polarizations align head-to-head, electrons that correspond to the sum of the polarizations are induced at the interface between the polar semiconductor and the ferroelectric layer. When the semiconductor is depleted, however, the polarization in the polar semiconductor aligns in the same direction as the polarization in the ferroelectric layer, whereas the polarization of the ferroelectric layer remains stable even under a depolarization field. This chapter describes the nonvolatile operation of the controlled-polarization-type FeTFTs resulting from the ferroelectric polarization reversal.

    © 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 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 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 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 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.
