Multifaceted Roles of Tantalum in Promoting the Thermoelectric Performance of Mg 3 (Sb,Bi) 2 Based Materials

Guangmeng You, Jingdan Lei, Kai Xu, Yuntian Fu et autres

ABSTRACT Mg 3 (Sb,Bi) 2 has emerged as one of the most promising thermoelectric materials with the potential to complement commercial bismuth telluride. However, its performance is still hindered by pronounced carrier grain‐boundary scattering, relatively high lattice thermal conductivity, and poor chemical …
