摘要
方钴矿热电材料具有优异的电输运性能,是热电器件核心部件最有前途的候选材料之一。热电器件需要性能相匹配的p型和n型方钴矿热电材料,然而p型方钴矿材料的热电性能和力学性能远低于n型方钴矿材料,因此提升p型方钴矿材料的热电性能和力学性能对于开发高效热电器件具有重要意义。本文总结了近年来在纳米-介观尺度调控p型方钴矿热电材料微结构的主要研究进展。通过微结构的调控可显著提升p型方钴矿材料的热电性能和力学性能,为热电器件的应用提供科学和技术支撑。
Skutterudite thermoelectric materials are one of the most promising candidates for critical components in thermoelectric devices because of their excellent electrical transport properties.Thermoelectric devices require p-and n-type skutterudite materials with matching properties.However,the p-type skutterudite materials have considerably worse thermoelectric and mechanical properties than those of n-type.Thus,it is important to enhance the thermoelectric and mechanical properties of p-type skutterudite materials for the development of high-efficiency thermoelectric devices.This study summarizes the recent research progress on the nano-mesoscopic scale regulation of the microstructure for p-type skutterudite thermoelectric materials.The thermoelectric and mechanical properties of p-type skutterudite materials can be notably enhanced by adjusting the microstructure at the nano-mesoscopic scale;thus,providing scientific and technical supports for the thermoelectric device's application.
