Thermal expansion and thermal conductivity of single-crystal CuxAg1-xInS2 solid solutions grown by the moving solvent method

Single crystals of CuxAg1 - xInS2 solid solutions are grown by the moving solvent method. The compositions and structures of the single crystals are determined. The thermal expansion coefficients of these crystals are determined with a dilatometer. The thermal expansion coefficients are found to vary linearly with concentration x. The thermal conductivity of the crystals is measured by the absolute method, and the concentration dependence of the thermal conductivity is constructed. This dependence is shown to have a minimum near the equimolar composition. (c) 2005 Pleiades Publishing, Inc.
