Paper Abstract

The results of theoretical analysis of influence of the photo-induced space charge upon the photo-carrier initiation, the Dember's effect (photo-EMF) and the photocurrent amplification in the case of inter-band absorption of weak 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 tasks (including the effect of the gigantic splash of semiconductor photoconductivity upon an increase in the concentration of recombination centers) are solved beyond the commonly used approximation of quasi-neutrality. It is shown that the solutions beyond the approximation of quasi-neutrality may be basically differed from the quasi-neutral solutions.
