摘　　要：Depletion of natural resources(oil,gas and coal)and increasing global warming urge the researchers to develop new methods for energy harvesting.The world’s demand of alternative clean energy is becoming more and more drastic.The conversion of waste heat into useful electrical energy is an eco-friendly and straight forward approach to solve the worldwide power problems.热电材料利用Seebeck与Peltier效应可以实现热能和电能的相互转化,是颇具潜力的新型功能材料.本文聚焦四元硫属化合物Cu2B^ⅡC^ⅣSe4(其中, B位为Zn, Cd, Mn, Hg, C位为Si, Ge, Sn)的热电性能.此类材料具有复杂的晶格结构,导致其具有较低的晶格热导率,是一类具有本征低热导的热电材料.本文系统地总结了各类优化四元硫属化合物电学及热学的方法.首先,非化学计量法、元素掺杂和η=1定理用于改善其电学性能.然后,纳米结构工程可用于进一步降低其热导率.最后,基于文中的论述,我们提出通过多种实验方法的结合使用,协同调控四元硫属化合物的电、热性能,以期进一步提高其热电性能.
