The first-principle calculation of the interaction of an edge dislocation with transition metal impurities Cr, Mn, Fe, Co, Ni and Cu in a supercell composed of 180 Si atoms is presented. The density functional theory in the general gradient approximation using the ABINIT software package has been used for numerical calculation. The interaction curves of edge dislocations with impurity atoms in silicon are obtained. The shape of the interaction curves corresponds to the Lennard-Jones potential. The equilibrium positions of impurity atoms in the vicinity of the edge dislocation cores are obtained. The binding energy of Cr, Mn, Fe, Co, Ni, Cu impurity atoms with an edge dislocation in silicon is calculated and analyzed. The electronic structure of the supercell with a dipole of two edge dislocations with Cr, Mn, Fe, Co, Ni and Cu impurities is presented. The general features of the electronic spectra for all impurity atoms are discussed. Due to the existing defective structure of the supercell, additional states appear in the band gap for all impurities, in particular, for Ni and Cu impurities, a sharp half-filled impurity peak is observed in the band gap. The intensity and fine structure of impurity peaks vary depending on the type of impurity and its position. The possibility of magnetic ordering on the dislocation core dangling bonds and Ni, Cu impurity atoms in the vicinity of the edge dislocation core has been discussed.

The experimental data on the ion-plasma (13.56 MHz) magnetron sputtering of composite targets of the system W-B are presented. Application of this method allows one to obtain deposited alloys in the entire concentration range of compositions. The as-deposited films show the formation of an amorphous solid state. The decomposition of an amorphous state is accompanied by precipitation of an intermediate meta-stable, nanocrystalline W-phase with FCC-structure. By applying magnetron sputtering, we have obtained an amorphous state in pure W-films at room temperature. The thermal stability, electrical and mechanical properties of metastable states in W-B films are studied. The study shows that the amorphous state in the WB 5 alloy is characterized by abnormally high temperature stability and microhardness. The ion-plasma sputtering method has demonstrated its effectiveness in the case of tungsten films, showing the possibility of obtaining metastable phases in them. At the same time, the obtained values of microhardness in the amorphous alloy turned out to be lower than the predicted maximum theoretical values due to the peculiarities of the location of atoms in the alloy.

The paper deals with the study of the effect of the morphology and structure of crystallites of p-Si layer on the adsorption of gas sensors. The porous layer was obtained by electrochemical anodization at anodizing current from10 to 60 mA and anodizing time from 5 to 30 min. The sensors were created as p-Si structures: PdAu-Si:GeAuNiAu by electron-beam evaporation. The porous layer surface was studied with optical microscopy, and the crystallite structure was examined with FTIR technique. It has been discovered that the anodization modes have a direct effect on the deformation vibrations of the SiHx group in wavenumbers from 700 to 950 cm – 1. At the boundaries of the crystallites, compressing stresses arise causing a decrease in Si–O–Si bond in wavenumbers from 1060 to 1160 cm – 1. It has been demonstrated the increasing effect of SiHn stretching bonds and SiOxHy complexes (absorption peaks at 2116 cm – 1 and 2340 cm – 1 respectively). The variation of anodizing time has a stronger effect on the structure of the porous layer than the variation of anodizing current. The adsorption sensitivity of the porous layer has been determined by the relative change in conductivity. The data obtained make it possible to conclude that the anodization mode affects the adsorption of gas sensors. This conclusion correlates with the data obtained with FTIR method in crystallites structure.
本文研究了p-Si层晶体形态和结构对气体传感器吸附性能的影响。在阳极氧化电流为10 ~ 60 mA,阳极氧化时间为5 ~ 30 min的条件下,采用电化学阳极氧化法制备了多孔层。采用电子束蒸发法制备了p-Si: PdAu-Si:GeAuNiAu结构的传感器。用光学显微镜对多孔层表面进行了研究,并用FTIR技术对晶体结构进行了表征。在700 ~ 950 cm - 1的波数范围内,阳极氧化方式对SiHx基团的变形振动有直接影响。在晶界处产生压缩应力,导致Si-O-Si键的波数从1060减少到1160 cm - 1。SiHn拉伸键和SiOxHy配合物的增加作用已被证明(吸收峰分别在2116 cm - 1和2340 cm - 1)。阳极氧化时间的变化比阳极氧化电流的变化对多孔层结构的影响更大。多孔层的吸附灵敏度由电导率的相对变化决定。所获得的数据使我们可以得出阳极氧化方式影响气体传感器吸附的结论。这一结论与FTIR方法获得的晶体结构数据相吻合。

The nanocomposite solid polymer electrolytes of Poly (ethylene oxide)/Polyvinylpyrrolidone doped with different concentrations (wt.%) of Zinc oxide nanoparticles (ZnO NPs) are prepared on quartz substrates using Spin-coat process. The Co-precipitation process is used to synthesize the ZnO NPs. The prepared nanocomposite polymer electrolytes were characterized by structural (XRD), morphological (SEM) and electrochemical (CV) studies. The spin-coating method is considered to be one of the most prominent due to the advantages of low cost and imperfection free uniform coating of resistant layers in the production of integrated circuits, surface coating and also acts as an intermediate insulator in different applications. The XRD analysis revealed the formation of nanostructures with (1 0 1) orientation in thin films which exhibits hexagonal Wartzite structure. All of the findings are correlated and discussed. The PEO/PVP/6 wt.% zinc oxide nanocomposite showed up to 500th cycles of reversible electrochemical response. The obtained results represent that nanocomposite solid polymer electrolytes based on ternaries are prominent materials for the use of transparent optoelectronic devices and solid-state batteries.
