Abstract

Surface conductivity of the thermoelements on a basis of the extruded samples of Bi_0.5Sb_1.5Te₃ and Bi₂Te_2.7Se_0.3 solid solutions and influence of the distorted surface layer, arising at manufacturing thermoelements on their bulk thermoelectric properties have been investigated over 77-470 K temperature range. It is found that thermoelectrical efficiency of thermoelements after treatment of a surface increases by 10-20%. The obtained results are explained by creating of the distorted layer of approximately 20 micrometers thickness on a surface of thermoelements in the course of their manufacturing.
