Abstract
The experimental results of electrical conductivity temperature dependence and photoconductivity spectra studies of Sn2P2S6 ferroelectrics are reported. It is shown that dark electrical conductivity have two states—high-resistive (background) and low-resistive (induced by preliminary light irradiation). The results are explained in the framework of the small-radius polaron model.Keywords
