The dimensional effects occurring in nanosized crystal layers under proton relaxation are studied by thermopolarization. The calculations are performed in the quasi-classical approximation using the density-matrix method.

The density matrix method is used for the description of the mechanism of proton tunneling under dielectric relaxation. As a result, a thermoactivation technique is proposed for the calculation of relaxation occillator parameters in hydrogen-bonded c

The nonlinear theory of thermally stimulated depolarization currents is developed. The theory explains the processes of hetero- and homocharge relaxation in complex crystals with hydrogen bonds and allows the relaxation oscillator parameters to be ca

The mechanism of proton migration over hydrogen bonds is considered. On this basis, a system of kinetic equations describing electret charge formation is written and solved in the linear approximation. The relaxation of heterocharge and homocharge is

The Bernal and Fowler model of ice [1] has been supplemented with modern ideas about relaxing defects arising as a result of migration of a proton along hydrogen bonds [2, 3]. We develop a theory for thermally stimulated currents (TSC) in hexagonal i

Using precision equipment of our own design, we measured thermally stimulated currents (TSCs) in pure crystalline ice and crystalline ice doped with HCl or NH4OH. The conditions for heterocharge and homocharge decay under thermally stimulated depolar

For the first time, the migration of ions inside a crystal in an electric field is explained by sequential proton transfer along hydrogen bonds and the anion sublattice. It is determined which ions are responsible for the low temperature dielectric r

A mathematical model is proposed for layered crystals, based on a system of kinetic equations describing the change in charged relaxation oscillators with time. An analytical solution of this system is found and a theory constructed, which allows det
