Description
Summary:Bi Te is a well-recognized material for its unique properties in diverse thermoelectric applications near room temperature. The considerable efforts on Bi Te -based alloys have been extremely extensive in recent years, and thus the latest breakthroughs in high-performance -type (Bi, Sb) Te alloys are comprehensively reviewed to further implement applications. Effective strategies to further improve the thermoelectric performance are summarized from the perspective of enhancing the power factor and minimizing the lattice thermal conductivity. Furthermore, the surface states of topological insulators are investigated to provide a possibility of advancing (Bi, Sb) Te thermoelectrics. Finally, future challenges and outlooks are overviewed. This review will provide potential guidance toward designing and developing high-efficient Bi Te -based and other thermoelectrics.
