Czochralski-grown single crystals of solid solutions based on Bi and Sb chalcogenides are advantageous, as compared with polycrystalline materials, when applied in fabricating highly miniaturized microcoolers: their use provides a much wider range of attainable temperatures and higher energy efficiency of thermoelectric cooling. These crystals have a rhombohedral tetradymite-type structure, space group R3m (D{sup 5}{sub 3d}), and exhibit perfect cleavage and a substantial anisotrophy in their electrophysical parameter along the in-plane and normal directions. We studied axial and radial homogeneity in 40-mm diameter crystals.
