摘　　要：随着环境和能源问题日益突出,利用热电材料将废热直接转换为电能,对于降低人类对化石能源的依赖起着重要的作用.目前,热电材料已应用于生物电源、光电器件、深空探测等设施.对纳米结构的热电材料进行了阐述,分析了纳米热电材料的结构特点、制备方法、晶格热导、声子散射、超晶格、热电性能及影响因素.探讨了进一步开发新型纳米热电材料的发展方向.Thermoelectric （TE）materials,which are designed to convert waste heat into electric energy, play an important role in reducing our dependence on fossil fuels, rITE materials have been applied to biothermal batteries to power heart pacemakers, optoelectronics coupled with solid-state TE cooling, and deep-space exploration via radioisotope TE generators. This paper pro- vides an overview of various nanostructured TE materials, and then conducts analysis on aspects including crystal structure, preparation methods,lattice thermal conductivity, scatter phonons, superlattice, thermoelectric properties and influence factors, with its highlights focusing on research criteria for developing new materials.
