Paper Title:

Thermoelectric Properties of Ni-Doped CoSb₃ Prepared by Encapsulated Induction Melting and Hot Pressing

Abstract

Ni-doped CoSb3 was prepared by the encapsulated induction melting and hot pressing, and its doping effects on the thermoelectric properties were investigated. Single phase δ-CoSb3 was successfully obtained by the subsequent heat treatment at 773K for 24 hours. Nickel atoms acted as electron donors by substituting cobalt atoms. Thermoelectric properties were remarkably improved by the appropriate doping.
