Abstract

Abstract The previously observed experimental difference in the thermal conductivity of gradient-inhomogeneous (variband) single-crystal samples of the Bi x -Sb1-x system in the case of parallel and antiparallel directions of the temperature gradients and composition in the semimetallic range of composition values (0.03 <x <0.10) under similar temperature conditions was also experimentally confirmed in other samples of this material having a composition in the interval of the semiconductor region (0.11 < x < 0.19). A theoretical model of the possible mechanism of this effect for the semiconductor region of the composition is proposed.
