Single-crystal films of solid solution Si1-xGex (0<x<1) were grown on Si<111> substrate from atin solution-melt at the temperature in the range of the onset of crystallization Tnc=(800−1050)°С by liquid-phase epitaxy. The perfection of the films obtained, as well as the dependenceof the dislocation density at the substrate-film interface on the number and size ofthe formed nanoclusters in the solution-melt during the growth of the Si1-xGex solid solutionhave been studied by X-ray method. Optimal technological growth modes for obtaining perfectcrystalline epitaxial layers and structures are presented.

In the paper, we numerically investigated the effects of the spectral shift in LED emission onthe pumping characteristics of LED-pumped lasers. We aim to illustrate how variations in theblue LED emission spectrum can…
The mass-charge spectra of multiply charged ions in a two-element laser plasma are studied bylaser ionization mass-spectrometry. The package of the mass spectrum of the Eu2O3 ions of thelaser plasma was obtained within…
A solar laser with an active medium of Ti:Sa/Nd:YAG composite structure has been studiedfor the first time using Monte Carlo photon tracing technique. The results show that the use ofan Nd:YAG active medium in…
A theory is developed of the inter band magneto-optical absorption of light in a nanodimensionalquantum well in a strong magnetic field due to interaction electrons with opticalphonons. We study the behavior of the…
The resource of fast-reading scintillator LuAG:Pr single crystals used in detectors for high-energyphysics is limited by fast neutron fluences ≥1016 cm−2 due to the accumulation of defect color centers.The purpose of…
The Faraday effect (EF) of single-crystal of dysprosium orthoaluminate (DyAlO3) was investigatedin the wavelength range 440–750 nm in the visible region of the spectrum at temperaturesof 90 K and 300 K. Magnetic…
In this work, interactions in biologically active active “butanoid (butyric) acid (BA)-acetonitrile/DMSO/pyridine/water” complexes and their spectral manifestations were studiedusing ab-ibitio calculations. When complex…
In the paper the catalogs of galaxy clusters are analyzed that have been published based on observationaldata to date. Based on the results of the study, a consolidated catalog was compiledcontaining 213 of the richest…
The issues of instability of individual oscillation modes for a nonlinear nonstationary model of collapsing galaxy clusters have been studied. The instability of the model with respect to two disturbance modes is…
The article presents the results of a photometric study of observational data of a four-componentgravitationally-lensed quasar GRAL J024848.7+191331 observed at the Maidanak Observatory.The light curves of the system as…
