Electric field and spatial charge formation in glasses and glassy nanocomposites

Journal of Applied Physics. 2011. Vol. 109. P. 094108.
Omelchenko A., Petrov M., Lipovskii A.

This paper concerns to rigorous analysis of the electrodiffusion problem arising during electric field treatment of glasses and glass metal nanocomposites (e.g. glass poling effect). The strict solution of the carrier drift equations for two type ions differing in mobility and diffusioncoefficient is obtained. This solution allows finding out the duration of space charge buildup and determining the limits of electroneutrality approximation. The rigorous solution demonstrates a good agreement with experimental data. The results of numerical solution are discussed as well.
