Abstract :
A simple analytical model is suggested for treating the intrinsic depolarization current density response in solid ionic conductors. The model deals with the localized hopping motion of mobile ions and describes quantitatively the microscopic energy landscape in which the mobile ions are embedded. The model is then compared to experimental data obtained by method of Thermally Stimulated Depolarization Current for two ionic conductors, i.e. a sodium silicate glass and a sodium zeolite.
