Electrical and Thermal Conductivity of Solid Solution Sn1–xMnxTe (0 ≥ x ≥ 0.04)

Abstract

Electrical and thermal properties of the Sn_1–xMn_xTe single crystals (0 ≥ x ≥ 0.04) with contacts of eutectic alloy 57Bi + 43Sn (in mass%) are investigated at temperatures from 77 to 300 K. Experimental results show that this alloy with specified single crystals forms ohmic contact with a sufficiently low contact resistance. The electronic thermal conductivity in some samples reaches about 50% of the total thermal conductivity, and structural defects contribute significantly to the thermal resistance of the crystals.
