Resolving the thermoelectric‐mechanical performance trade‐off in n ‐type Bi 2 Te 3 ‐based compounds via a novel melt‐spinning and hot‐extrusion route

Jinglian Fan, Junjie Li, Wei Wei, Tingting Luo et autres

Abstract Bi 2 Te 3 ‐based materials are the best commercial thermoelectric (TE) materials for applications near room temperature. However, zone‐melted (ZM) materials suffer from poor mechanical properties, while traditional powder metallurgy‐derived Bi 2 Te 3 exhibits a strong donor‐like effect when …

The role of surface oxygen chemisorption on impurity states and electron localization in n-type PbTe: Ar-protected grinding as a remedy for tripling ZT

Yingfei Tang, Keke Liu, Wei Wei, Shujun Han et autres

O 2 physically adsorbs on defective PbTe, and then activates as the OO bond lengthens. Upon dissociation, one O atom occupies a V Te site. After lattice relaxation, the system stabilizes into a final O Te + V Pb defect complex.
