Abstract

The influence of temperature (in the interval of 300–400 K) and concentrations on the electrical conductivity, thermal conductivity, and thermoelectric power of copper chalcogenide-based crystals with the general formula (GeSe)_{1 – x}(CuAsSe₂)_x has been considered. Heat transfer mechanisms have been determined. It has been found that the temperature dependence of thermal conductivity is nonmonotonic with a singularity at 358 K. Thermoelectric figure of merit ZT has been calculated.

摘要

温度的影响（在300-400 K的间隔），并且在导电性，导热性，以及热电发电铜基于硫族化合物晶体与通式浓度（GESE）_{1 - X}（CuAsSe ₂）_X一直经过考虑的。已经确定了传热机理。已经发现，导热系数的温度依赖性是非单调的，在358 K时具有奇异性。已经计算出热电因数ZT。
