Dispersive Orientational Dipole Relaxation in Thermally Stimulated Depolarization Currents

Abstract

We show that dipole orientational relaxation in thermally stimulated depolarization currents (TSDC) from alkali-containing glass can be explained by requiring broad distribution of dipole relaxation events. This requirement originates in the structural disorder of the material. Shlesinger-Montroll's theory in the framework of continuous-time random-walk is applied to the case of dispersive rotational motions of dipole relaxation. The Williams-Watts function is obtained for orientational dipole decay. The TSDC is calculated and is in good agreement with our experiment.
