Abstract

We study experimentally the photorefractive gratings decay in semi-insulating germanium doped cadmium telluride crystals. The estimates for the diffusion length of free carriers L_D and for Debye screening length l_s, for dark and photoconductivities of the sample are done from the angular and intensity dependences of the time constant.
