Abstract

The effect of the non-steady-state photoelectromotive force (PEMF) in photoconductive crystals is considered for excitation frequencies equal to or higher than the inverse photocarrier lifetime. The theoretical analysis, based on a widely used model of an impurity photoconductor with one partially compensated donor level, is performed for the case of an external dc electric field applied to the sample. The average lifetimes of photoelectrons and their mobilities are estimated from experiments on the PEMF in cubic BSO and BTO crystals.
