A new class of quasireflectionless potentials, associated with low energy scattering, has been considered. The effective parameters of low energy scattering have been determined using the system expansion by the wave vectors in the region of the para...
Some peculiarities of the controlled rearrangement of charge carriers in the nanostructures based on the tunnel-connected quantum regions, formed by GaAs/AlGaAs heterojunctions, have been considered. The results of numerical modeling of the wave func...
The comprehensive analysis of the problem of appearance of the carbon inclusions in the silicon carbide monocrystal during growing the silicon carbide ingots by the modified-Levy method (so called ingot graphitization) has been presented. It has been...
Some more precise expressions, allowing the computation of the complex components of magnetic permeability tensor of poly- and monocrystal microwave ferrites with different magnetization extent, have been proposed. The expressions take into account t...
It has been found that the bandgap of anode Cu2O containing 5 at.% Cl is 1,8 eV. It has been shown that the resistance of the chlorine-containing Cu2O resistors is almost 5 orders reduced in the 20-75° temperature range and is 2 times exponentially d...
The results of investigating the compositions for manufacture of the thick-film resistive elements with high-temperature coefficient of resistance (TCR) for application as thermo-resistive gauges have been presented. In the investigated compounds a p...
The optimization procedure in growing the layers of A3N nitrides by MOCWD method using the X-ray-diffractometry method has been considered. It has been determined that the structural perfection of the layers, obtained by measurement of the rocking wa...
Self-heating effects and heat sink problems in lateral power SOI-MOSFET's have been studied. Using the process and device simulation TCAD tools the output characteristics and safe operation area have been simulated. It has been shown that the safe op...
The gas damping influence on bandwidth of the pendulum microaccelerometers has been investigated. It has been found that to increase the bandwidth, it is necessary to provide residual pressure of not higher than 1-5ּ10-1 torr inside the packaged devi...
The results of mathematical modeling of the light distribution in a gas optical sensor based on planar multimode waveguide (d >> λ) have been considered. In the proposed construction upon the waveguide small surface area a homogeneous substance...
