Abstract
The effect of temperatures (300 - 400 K) and concentrations on electrical conductivity, thermoelectric power, and thermal conductivity of crystalline materials based on copper chalcogenides with the general formula (GeSe)1-x (CuAsSe2)x is analyzed. The mechanisms of heat transfer are determined. The non-monotonicity of the temperature dependence of the thermal conductivity with an anomaly at 358 K. The thermoelectric figure of merit ZT is calculated.
