AbstractThe equilibrium distributions of the misfit dislocation density ρ(z) and elastic stresses ε(z) are calculated along the direction of the epitaxial growth of the metamorphic InAlAs/GaAs(001) layer with higher In content (to 87 mol %) and various profiles of varying the composition: step, linear, and root. The calculations are performed using...

AbstractThe behavior of localized plastic flow autowaves in a Fe–Ni–Cr alloy at temperatures 143 K ≤ T ≤ 420 K is considered. The temperature variation of the autowave propagation velocity is studied. It is found that, for the region of low temperatures, the autowave velocity is inversely proportional to the work hardening coefficient and the quadr...

AbstractThe effect of the solution acidity on the crystal structure of cobalt during its chemical deposition is reported. It has been shown using the structural and magnetic examination and nuclear magnetic resonance study that the change in the working solution acidity leads to deposition of cobalt with different allotropic modifications in the ne...

AbstractThe critical current of a model high-temperature superconductor (HTSC) with defects in the form of through holes (antidots) with characteristic sizes on the order of the magnetic-field penetration depth (or larger) is calculated. To this end, subprocesses equivalent to the magnetic-flux trapping by a hole and creation of a vortex near the h...

AbstractThe “temperature–defect concentration” phase diagram of quasi-one-dimensional Ising models with defects of the “random local field” type is studied. The competition of the tendency to the formation of a long-range order due to a weak interaction between one-dimensional spin chains and the tendency to the formation of the Imry–Ma phase in wh...

AbstractIn this research, the solution casting technique has been used to synthesize composite with different weights of VCl3 embedded in polyvinyl alcohol (PVA), in the form of films. X-ray diffraction (XRD) patterns display a broad peak with low intensity of high doping composite films, reflecting an increase in the non-crystallinity and the inte...

AbstractThe computer simulation methods have been applied to calculate structure and energy of symmetric tilt grain boundaries (GB) with the misorientation axes [110] and [111]. The calculations have been carried out with the use of the structural-vacancy model. The study of the atomic structure has been carried out within the entire range of misor...

AbstractFormulas of efficient relaxation time are obtained for the cases when the free length of electrons is less or comparable with the characteristic dimensions of metallic regions. The frequency dispersion of optical characteristics of spherical bimetallic particles is calculated near plasma resonance in the absence of quantum-size effects. Ret...

AbstractCompact waveguide laser sources emitting at wavelength around 1.0 μm are interesting in a multiple of application. In present work, we demonstrate a crystalline waveguide in Yb:Lu3Al5O12 (Yb:LuAG) crystal irradiated by 4.5-MeV Si ions at fluences of 1.0 × 10–15 cm–2. A typical “barrier-confined” waveguide geometry is confirmed by performing...
