The laser generation of sound waves in strongly absorbing liquids is discussed. We demonstrate the experimental method to determine simultaneously both velocity of sound and light-absorption coefficient in liquids. With ...

The work describes the capabilities of laser scanning microscopy (LSM) as a spatially-resolved method of testing high–Tc materials and devices. The earlier results obtained by the authors are briefly reviewed. Some novel ...

In this work, features of solar cells of lateral type were analyzed. The authors offered a design of a monolithic compact solar module with cells electrically connected in series and with a dispersion element (holographic ...

The hcp lattice distortion parameter δ, the deviation of c/a ratio from the ideal hcp value √ 8/3 , have been calculated for solid He under pressure taking into account two- and three-body interatomic forces. The resulting ...

The phonon dispersion relations in a CsH₂PO₄ crystal in a paraelectric phase by means of a rigid molecular-ion model are calculated. The phonon spectra in the quasi-harmonic approximation at various values of temperature ...

The thermodynamics of a lattice model of intercalation of ions in crystals is considered in the mean-field approximation (MFA). The pseudospin formalism is used for the description of the interaction of electrons with ions, ...

Combining Little's and Ginzburg's ideas with recent progress in nanotubes research, a novel type of material is advanced as a perspective high-Tc superconductor on base of a close-packed lattice of quasi-1D superconducting ...

Electrophysical parameters of Hg₁₋xCdxTe thin films grown by liquid-phase epitaxy and molecular-beam epitaxy were investigated before and after the high-frequency sonication ( fUS = 7.5 MHz, WUS ~ 10⁴ W/m²). It was determined ...

State-of-the-art condition of LED illumination engineering for street lighting, its requirements, construction technological features of its creation, optimization ways of optical, thermal and electrical luminaire ...

We study numerically the form of the critical line in the disorder–magnetic field phase diagram of the p–q network model, constructed to study the levitation of extended states at weak magnetic fields. We use oneparamet ...
