BiTe-SbTe-SbSe-BiSe SOLID SOLUTIONS OF N- AND P-TYPES OF CONDUCTIVITY WITH INCREASED MECHANICAL STRENGTH Russian patent published in 2022 - IPC H01L35/16 C22C12/00

Abstract RU 2774636 C1

FIELD: thermoelectric energy conversion.

SUBSTANCE: invention relates to the field of thermoelectric energy conversion, in particular to a thermoelectric material in the form of a Bi₂Te₃-Sb₂Te₃-Sb₂Se₃-Bi₂Se₃ solid solution containing alloying additives. Thermoelectric material in the form of solid solutions (Bi₂Te₃)(15-94)-(Sb₂Te₃)(60-85)-(Sb₂Se₃)(0-10)-(Bi₂Se₃)(5.9-14) contains germanium dopant in the amount of 0 .01-0.12 wt. % and a dopant of chlorine, bromine or iodine in the amount of 0.01-0.19 wt.% or dopant lead in the amount of 0-0.1 wt.%.

EFFECT: increase in physical and mechanical strength.
