HIGH FIELD TRANSPORT PROPERTIES OF ZnS AT DIFFERENT TEMPERATURES

Abstract

Electron-phonon interactions in ZnS are studied. Based on these results, high field transport processes at different temperatures are investigated by means of Monte Carlo method. The transient acceleration time of electrons do not vary with temperature. As the temperature increases, the kinetic energy distribution shifts to lower energy side and the average kinetic energy drops. The intervalley distribution of electrons shifts to lower valley as the temperature increases. The drift velocity of electrons decreases with increasing temperature. The detailed changes of these parameters with temperature are also given in this article.
