Paper 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 LD and for Debye screening length ls, for dark and photoconductivities of the sample are done from the angular and intensity dependences of the time constant.
