A procedure for growing perfect single crystals of bismuth antimony chalcogenide solid solutions by the Czochralski technique with melt feeding from a floating crucible was developed at the Baikov Institute of Metallurgy. Given that the single crystals in question readily split along the cleavage planes, the problem of acceptable yield of suitable products in the manufacture of thermoelements and cooling modules arises. To solve this problem, investigations were undertaken along two lines: (1) development of nondestructive, damage-free technologies; and (2) development of methods for making low-resistance antidiffusion contacts on the end faces of the thermoelements.
