摘　　要：Thermoelectric materials have drawn much attention in decades due to their applications in sustainable power generation or electronic cooling,originating from the unique ability of direct conversion between heat and electricity[1-4].The reversed conversion from electricity to temperature difference can also be applied for cooling[5-8].热电材料能够实现热能和电能的直接相互转化.铅硫族化合物是传统中温区热电材料.随着对低成本热电材料应用需求的增加,提高铅硫族化合物在宽温度范围内的热电性能已迫在眉睫.最近,一种实现高近室温热电性能的新方法得到了广泛的研究,特别是在铅硫族化合物中,该方法致力于提高载流子迁移率.总结最近在实现高载流子迁移率方面的工作至关重要.鉴于此,我们概述了三种提高铅硫族化合物载流子迁移率的策略,包括空位补偿、轻掺杂和晶体生长.此外,还列举了具体实例来证明这些策略的实用性.这些通过载流子迁移率提升铅硫族化合物热电性能的研究成果为在其他热电材料实现高热电性能提供了新途径.
