Abstract

In this paper an analysis of the lattice limited mobility of electrons in CdS as well an analysis of the carrier concentration dependence of the room temperature mobility is presented. It is shown that the lattice mobility of electrons can be very well described by the combination of polar optical phonon, deformation potential and piezoelectric scatterings in a very wide temperature range. The room temperature mobility vs carrier concentration curves are calculated for combined ionized impurity and lattice scatterings, with different degrees of compensation. The calculated curve for negligible compensation agrees well with the relevant experimental data.
