Abstract
In this paper the frequency phase characteristics of the photothermal piezoelectric signal of a few AII-BVI mixed crystals are presented and discussed. The following groups of crystals were analyzed: Zn_1-xBe_xTe, Zn_1-xBe_xSe, Cd_1-xMg_xSe and Cd_1-xMn_xTe. From the fitting procedure the concentration dependence of the thermal diffusivity of these mixed crystals was determined.
