- Abstract
generalized problem of positive ion transfer in a dielectric under the action of an electric field in the presence of diffusion and a flux of other positive charge carriers with different mobilities entering into the medium is considered based on the diffusion equation and the Poisson equation. A strict system of equations is written and its numerical solution is obtained in cases where the ions and other carriers possess (i) significantly and (ii) insignificantly different mobilities, which correspond to the poling of glasses and the electrostimulated ion exchange, respectively. The obtained temporal dependences of the depth of a modified region and the electric field (in normalized coordinates) well agree with data available for particular cases.
