文摘

The influence of the photoexcitation intensity on the value of the stationary photocurrent in pure and Li-doped pyrolitic CdS films with a nanostructured surface has been studied. The brightness dependence of the photocurrent of the structures under study is approximated by a power function whose power index is a decay function of the excitation intensity. The unusual peculiarity of the photocurrent dependence on illumination intensity is explained by a modulation of the surface potential barriers for the drift and recombination of nonequilibrium charge carriers.
