SnTe基热电材料及器件的研究进展与展望
Research Progress and Prospects of SnTe-Based Thermoelectric Materials and Devices
摘要
Abstract
SnTe materials are of interest in the thermoelectric field due to their environmentally friendly,non-toxic properties and multivalent band structure.Currently,the thermoelectric figure of merit of SnTe has been significantly improved through carrier concentration optimization,band structure engineering,and multi-scale defect construction.Following interface material design and welding process optimization,SnTe-based thermoelectric modules with conversion efficiencies of about 10%have been developed.This review begins by examining the crystal and electronic band structure characteristics of SnTe.It then details strategies for optimizing the strategy of SnTe-based materials,discusses the challenges associated with selecting interface materials for SnTe-based devices,and summarizes the construction approaches of SnTe-based thermoelectric devices.Finally,it presents an outlook on the future research for SnTe thermoelectric materials and devices.关键词
