Abstract: Disclosed in the present disclosure are a P-type bismuth telluride-based material and a method for preparing the P-type bismuth telluride-based material. The P-type bismuth telluride-based material is doped with a rare earth element, and prepared from a rare earth material, a Sb source, a Te source and a Bi source by melting, ball milling and sintering.
