Alloy Disordering Effects on the Thermal Conductivity and Energy Gap Temperature Dependence of Cd<sub>1−x</sub>Zn<sub>x</sub>Se Ternary Crystals Grown by the Bridgman Method
Abstract
Investigated in this work, Cd1−xZnxSe-mixed ternary compounds were grown by the Bridgman method. Several compounds with zinc content varying in the range 0 1−xZnxSe alloys were systematically studied. The thermal diffusivity and effusivity of the crystals under investigation were experimentally determined, allowing the calculation of the thermal conductivity. We applied the semi-empirical model that Sadao Adachi developed to analyze the results. Thanks to that, it was possible to estimate the contribution arising from chemical disorder to the crystal’s total resistivity.
