Paper Abstract

The results of theoretical analysis of influence of the photo-induced space charge upon the Dember's effect (photo- EMF) in the case of inter-band absorption of low-intensity optical radiation and non-equilibrium carrier recombination via deep impurity are presented. The model of a single recombination deep acceptor level and shallow donor impurity is considered. The task is solved beyond the commonly used approximation of quasi-neutrality. It is shown that the solution beyond the approximation of quasi-neutrality may be basically differed from the quasi-neutral solutions.
