The one-dimensional model of ionic conductivity in dielectric layers with a non-uniform blocking surface of the semiconductor with specified geometrical horizontal structure is developed. The model is based on the results of research of a relaxation of ions in dielectric on polycrystalline silicon and allows predicting behavior of ions depending on a roughness of border.

Nowadays the Internet is a highly developed communication system. Every day the number of the users of the Internet increases for thousands of people. This system is open for everybody: either a law- abiding and decent person or a quite opposite one. This leads to such problems of the defense of information as copyright and transmission of hidden messages via World Wide Web through open communication channels. This article covers methods, which can help to solve these problems with usage of text steganographic algorithms.

In the present study, low-temperature electronic transport in Pb 1-x Sn x Te:In films with prevailing contact injection of charge carriers was examined. Data concerning the influence of magnetic field on the injection currents, and also on the transient currents observed following turn-on and turn-off of the field are reported. Possible mechanisms of observed phenomena are discussed.

By means of numerical modeling research of structure dual-collector bipolar magnetosensitivity n-p-n transistor in diffusion well of p-type with topology of elements: the emitter-base-collector was carried out. The analysis of proceeding currents through electrodes of the transistor has shown that relative magnetic sensitivity has a negative range. It is carried out research of influence of control voltage between electrodes of the transistor on change of a sign and size relative current sensitivity. The factors leading increase of magnetic sensitivity of transistors and change of a sign of a target signal by numerical calculations are established.
