Methods of theoretical researches the non-linear electrophysical properties of solid dielectrics with compound crystalline structure

Abstract

Abstract Methods quasiclassical kinetic theory investigate the phenomena of nonlinear ion-relaxation polarization in solid dielectrics with a compound structure of the crystal lattice. As a particular case, the mechanism of nonlinear proton-relaxation polarization in hydrogen-bonded crystals (HBC), classified according the electrophysical properties as proton semiconductors and dielectrics (PSD) is theoretically studied. Generalized kinetic equation and spectra of complex permittivity (CP), which allow to describe the nonlinear properties of dielectric losses in HBC in range of ultra-low temperatures (1- 10 K) and low fields (100 kV/m - 1000 kV/m), and in range of ultra-high temperatures (550-1500 K) and strong fields (10 MV/m - 1000 MV/m). The scientific and practical significance of received results consists in development of the theoretical basis of algorithm for computer prediction of materials properties and parameters that are functional elements of technological schemes of industrial installations and systems.
