In this paper a method for an approximation of electro-optical characteristics of a cholesteric liquid crystal (ChLC) that describe behavior of a cholesteric material at transitions from the field induced homeotropic texture ...

An analysis of the 4.2 K exciton luminescence spectra of semi-insulating GaAs crystals with different concentrations of shallow acceptors (С) and donors (Si) is given. As a result, the 4.2 K capture coefficients of free ...

The influence of longitudinal manetic field (MF) on a position of polarization planes (PPs) of the main modes (λ = 0.63 mm) in dependency on the generation frequency and off-axis mode presence was investigated in this work. ...

In digital information error happens in a communication system due to path delay or processing error/delay and can be detected by logical circuit which has been implemented here by binary decision diagrams with single ...

A spatial distribution of the cation vacancy related defects and their influence on the formation processes of self-assembled nanoislands in CdSe/ZnSe heterostructures were investigated by photoluminescence methods. ...

We studied possibilities of a nondestructive X-ray technique for testing short-period strained GaAs-AlAs superlattices. An analysis of the quasi-forbidden 200 reflections may be used for determination of superlattice layer ...

A possible mechanism of the photoinduced luminescence degradation in the hexagonal CdSxSe₁₋x quantum dots synthesized in a glass matrix is discussed using luminescence decay kinetic investigations and ab initio calculations ...

Noise-induced escape from the metastable part of potential is considered on time scales preceding the formation of quasiequilibrium within that part of the potential. It is shown that, counterintuitively, the escape flux ...

Ellipsomety examination of dielectric sheetings and measured of reflection spectrum at normal incidence there carried out. A film of Al₂O₃ on a surface of copper mirrors of a diamond microgrinding was deposited. The thickness ...

We propose the theory of the micro-domains (MD) formation in ferroelectric photorefractive crystals appeared under steady illumination by laser beam perpendicular to the polar axis. The crystal has the donor level made ...
