Abstract

Tne present paper is devoted to the experimental study and the analysis of photoferroelectric phenomena in ferroelectric-semiconductor Sn2P2S6 crystals and films. These photoactive light-induced phenomena observed in polarized Sn2P2S6 samples are described by the model of screening the depoling field of remanent polarisation by free charge carriers fixed at the deep energy levels.
