THERMAL-DIFFUSIVITY AND CONDUCTIVITY OF HG1-XZNXTE SOLIDS AND MELTS

The thermal diffusivity of pseudobinary Hg1-xZnxTe solids and melts wa s measured by the laser flash method. The measured diffusivities for t he solids of 0.10 less than or equal to x less than or equal to 0.30 a re about 60% of that of the HgTe solid. Those for the melts rise rapid ly with temperature but less so with increasing x. For x=0.30, the dif fusivity of the melt is about one third of that of the HgTe melt. Usin g the calculated heat capacity data from the associated solution model and measured density values, the thermal conductivity for the pseudob inary Hg1-xZnxTe solids of 0.10 less than or equal to x less than or e qual to 0.30 and for the melts of x = 0.10, 0.16, and 0.30 was determi ned.
