Indium impurity effect on growth and structural perfect of lead-tin telluride wire crystals

Abstract

In this work, we present the results of studying the indium impurity effect on the structural perfection of wire crystals (WCs) of the Pb0.8Sn0.2Te solid solution, which were obtained by sublimation in quartz capillaries. The microscopic and X-ray investigations revealed that indium doped lead-tin telluride single crystals with uniform distribution of indium impurity can be grown by the zone sublimation method. The relationship between the method of treatment of the surface of indium doped lead- tin telluride WCs of the Pb0.8Sn0.2Te solid solution and the density of structural efects, microhardness, and electric parameters was found.
