    <p>Alloys between different kind of metals on surfaces often exhibit novel structures comparing to those in the bulk. For example, Ni and Au do not form alloys in the bulk form, but Au adsorbed on the topmost surface layer of Ni is known to induce surface two-dimensional alloying by replacing some of the Ni atoms on the surface with Au [1]. Since ultrathin films on metal surfaces will a unique structure, it will have high expectations for the discovery of a novel growth modes from the conventional thin film growth modes (FM, VW, SK) and for the development of new functionalities.</p><p></p><p>It is known that Ni-Ag, like Ni-Au, does not mix atoms in bulk form, and that Ag thin films on a Ni(111) surface grow in layer-by-layer and form a moire pattern due to the lattice mismatch [2], and that Ag(111) is formed on a Ni(100) surface has been confirmed in our laboratory. Although there have been many studies on metal heteroepitaxial growth by STM since the 1990s, there have been few observations of thin films of fcc metals at the atomic level, and the growth pattern of thin films, including interdiffusion and alloy formation, has not been clearly established at present. In this study, we studied the Ag-induced surface structures on the Ni(110) surface (Ni(110)-Ag) that has not been observed by ultra-high vacuum scanning tunneling microscopy (UHV-STM) and low-energy electron diffraction (LEED), depending on the growth and annealing conditions.</p><p></p><p>UHV-STM observation of the Ag-deposited surface on Ni(110) substrates at room temperature showed that Ag did not alloy with the substrate Ni atoms, but formed a reticulate structure. When deposited at 200°C, the reticular structure was aligned to form a stripe structure along the [001] direction. A 10×10 nm<sup>2</sup> STM image (Fig. 1) of the RT deposition shows that three regions coexist. Region A is a bright region with a periodic protrusion in the [001] direction, which corresponds to the substrate atomic rows. Therefore, Ag atoms are considered to grow epitaxially in the [11-0] direction to form bright bands in the [001] direction. They occasionally form wavy structures with a 3× periodicity in the [11-0] direction. Region B is noisy, where Ag atoms do not match the periodicity of the substrate in the [11-0] row and they are considered to fluctuate in the row. Region C is a trough structure with a depression of about 120 pm and is considered to be a region where no Ag atoms exist.</p><p></p><p>LEED observation showed one-tenth of the satellites spots near integer-order spots of the Ni(110) 1×1 structure in the [11-0] direction, indicating that epitaxially grown Ag atoms have a super structure along the [11-0] row.</p><p></p><p>References</p><p>[1] L.

    <p>First-principles total-energy calculations were applied to 0 to 1 ML of silicon-embedded Ni(100) surfaces in the outmost layer within a 2 × 4 unit cell. Up to a half monolayer of embedded silicon, the surface energy decreased monotonically with increasing the number of embedded silicon, and the lowest energy structure was a √2 × √2-R45° [or c(2 × 2)] structure with diagonally aligned embedded silicon of 0.5 ML. Beyond the half monolayer, the surface energy increased with increasing the number of embedded silicon. The energy of the silicon-embedded structure in the outmost layer of the Ni(100) surface was compared with silicon embedded in the second layer and silicon adsorbed on the Ni(100) surface. Both configurations gave higher energies, which shows the robustness of the √2 × √2-R45° structure on the Ni(100) surface. The present results are in perfect agreement with our recent report [T. Fukuda <i>et al.</i>, Jpn. J. Appl. Phys. <b>59</b>, 065501 (2020)].</p>

He proposed a pressure boundary between the exponential decrease and the reciprocal decrease as a “Bifurcation pressure”. We experimentally found bifurcation pressures and they quantitatively compered with the theoretical estimation. The result of our experiment agreed fairly well with values that had been obtained by the theoretical calculation.</p>

    Initial silicide formation on a Ni(110) surface was studied by scanning tunneling microscopy (STM) in an ultrahigh vacuum. Less than 0.5 ML of Si deposition initiated a Si-Ni mixed layer by displacing substrate Ni, and dark sites were formed in the STM images. A 0.5 ML-Si deposited surface showed that Si and Ni were alternately aligned in a close-packed [11¯0] row whereas Si pairs aligned along the [001] direction forming p(1×2), obliquely aligned forming c(2×2), or even straightly-and-obliquely aligned forming c(4×2) superstructures. A first-principles total energy calculation showed that the p(1×2) and c(4×2) structures had almost the same energy while the c(2×2) structure gave 13 meV/1×1 higher energy. Because a Si-Si bond in the close-packed [11¯0] row is energetically unfavorable, Si deposition of more than 0.5 ML did not further replace the substrate Ni, but silicide islands were nucleated along with a trench structure.

    <p>First-principles total energy calculations were performed to investigate stable atomic structures for the displacive adsorption of silicon on the Ni(110) surface. Gibbs free energies were compared for 0-4 silicon atoms embedded into the top layer in a 2×2 unit for the Ni(110) surface. When a half monolayer of Si was embedded, the p(1×2) structure had the lowest energy, and the c(2×2) structure had only 13 meV/1×1 higher energy than the p(1×2) structure. By extending to a 4×2 unit, the c(4×2) structures had almost the same energy with the p(1×2) structure. Alternating Si-Ni chains along the close-packed [1-10] row play an essential role to stabilize these structures. Si and Ni are alternatively aligned in separate [1-10] rows forming a p(2×1) structure, which had 276 meV/1 1 higher energy than the p(1×2) structure. For the p(2×1) structure, unique one-dimensional electronic bands derived by the Si-3<i>s</i> states were formed along the [1-10] direction. [DOI: 10.1380/ejssnt.2017.96]</p>

    Cu overlayer formation on the Ni(110) surface was studied using scanning tunneling microscopy (STM) in an ultrahigh vacuum. Room-temperature deposition of Cu onto a Ni(110) surface exhibited layer-by-layer growth up to 6 monolayers (MLs), followed by three-dimensional island formation, i.e., the Cu overlayer growth on the Ni(110) surface is classified as Stranski-Krastanow growth. At the initial growth stage, anisotropic two-dimensional islands were elongated in the close-packed [11̄0] direction. The nucleation of the second layer was strongly affected by the morphology of the first layer, and the second-layer islands also extended in the [11̄0] direction. The third and further layers grew two-dimensionally. Detailed STM images showed mosaic features due to Cu and Ni alloying. Three-dimensional islands were observed for Cu deposition beyond 6 ML. The (110)-oriented top surface of the islands had stripes along the [001] direction. In addition, bumps extending in the [11̄0] direction were formed on these island surfaces, indicating threading dislocation through the island to relieve the compressive stress of the overlayers. An atomic model of the bump compatible with the STM image was proposed. © 2012 Elsevier B.V. All rights reserved.

    The atomic geometries and electronic band structures of Cu-embedded Ni(110) surfaces were studied theoretically. First principles calculation with spin-resolved local density functional theory was applied to the Ni(110) surface, and one to four Cu-embedded Ni(110) surfaces in the 2×2 surface unit cell. The optimized structures for the Ni(110) surface showed that interlayer spacing between the first and the second layer shrunk 11.1% of the bulk distance, but the second and third layer spacing expanded by 2.9% in agreement with previous studies. For the Cu-embedded surfaces, embedded Cu atoms are 11-14 pm higher than the top Ni atoms, which is about four times larger than the difference of the atomic radii. The detailed band structures and corresponding local density of states (LDOS) were calculated. At the embedded Cu atom sites, the surface LDOS near the Fermi level was reduced in agreement with previous scanning tunneling microscopy observation. In addition, by increasing the number of Cu atoms in the top layer, magnetic moments were decreased near the surface regions. [DOI: 10.1380/ejssnt.2009.681]

    We studied initial Cu overlayer formation on the Ni(110) surface by scanning tunneling microscopy (STM) in an ultrahigh vacuum. Initially, deposited Cu displaces the top Ni layer, forming two-dimensional Cu-Ni alloy on the substrate. The Cu atom embedded into the top layer was depressed in the STM image. The depression due to the lack of Ni 3d-derived surface local density of states was confirmed by the first-principles calculation. Ni atoms squeezed out from the top substrate layer agglomerated in the anisotropic Ni island along the close-packed (1 (1) over bar0) direction. Further Cu deposition resulted in a Cu-Ni mixed island. Quantitative measurement of the Cu fraction on the substrate showed that 0.71 +/- 0.04 of deposited Cu was embedded in the top Ni layer, whereas significant Cu enrichment was seen on the island.

    Copper overlayer formation on the Ni(1 1 0) surface was studied by scanning tunneling microscopy (STM) in an ultrahigh vacuum. Atom-resolved STM images showed that initially deposited Cu is replaced with surface Ni atoms forming atom-size depressions on the Ni(1 1 0) terraces and a Ni-rich quasi-one-dimensional island along the [1 (1) over bar 0] direction. Further Cu deposition yields a mosaic structure on the islands, indicating Cu/Ni mixed layer formation. From the quantitative measurement of the Cu/Ni ratio on the substrate and the islands, impinging Cu will be replaced with surface Ni whereas expelled Ni and directly impinging Cu to the island form the mixed island. The number of Cu atoms in the islands, however, more than the directly impinging Cu, indicate significant Cu/Ni replacement at the periphery of the island. (C) 2008 Elsevier B.V.

    Initial hydrogen adsorption on the Si(111) 7 x 7 surface was studied by scanning tunneling microscopy (STM) in an ultrahigh vacuum. Room temperature adsorbed hydrogen on the adatom in the 7 x 7 reconstruction led to depression of adatoms in the STM images. The hydrogen uptake curve at the adatom site as a function of hydrogen exposure time was well represented by Langmuir adsorption. No preferential adsorption was seen among four inequivalent adatoms in the 7 x 7 reconstruction. Adsorption of the adjacent center and corner adatoms respectively showed similar to 10% higher adsorption. Even though the number of reacted adatoms in the half unit of the 7 x 7 reconstruction was statistically random, the number of reacted adatoms in the nearest neighbor half unit was enhanced as the number of reacted sites increased in the half unit.

    We performed in situ scanning tunneling microscopy observation of oxygen reaction on the Si(111)7×7 surface at high temperatures. In spite of passive oxidation regime, we found that voids having the depth just one bilayer were formed at the initial stage of reaction. We found that the number density of the void was well represented by power laws. We applied the two-dimensional nucleation theory to this void formation and found that the critical nuclei were <i>i</i> = 1.46(647 K) and <i>i</i> = 14.7(751 K). We found the transition from active to passive oxidation with constant substrate temperature and oxygen exposure rate. The transition was quantitatively reproduced by the numerical simulations.
