Abstract
Mg₃Sb₂-based n-type materials are consisted of earth-abundant elements and possess comparable thermoelectric properties with n-type Bi₂Te₃ at low temperatures, which make them promising candidates for cooling and power generation applications in terms of cost and performance. Substitution of Sb atom with chalcogen elements (Te, Se S) is a conventional method..... More

Abstract
Cu₃Sb_1–x–yGe_xIn_ySe₄ (0.02 ≤ x ≤ 0.12; 0.04 ≤ y ≤ 0.08) permingeatite compounds doped with Ge and In were prepared using solid-state synthesis. The phases and microstructures were analyzed, and the charge transport and thermoelectric properties were evaluated according to the Ge and In doping content. Most of the samples..... More
