纤锌矿氧化锌(ZnO)是一类性能优异的高温热电材料,在航天飞行器和太阳能温差发电方面具有广阔的应用前景. 如何最大限度地提高材料的热电优值(ZT值)是当今热电材料研究的主要问题,常通过对电子和声子输运性能的综合调控,以达到热学性能和电学性能的协调统一来获得最优ZT值.文章综述了纤锌矿ZnO基陶瓷和纳米结构材料的热电性能研究进展,重点介绍了研究工艺、掺杂和量子限制效应等方法对电子和声子输运的调控结果,分析了其对提高ZT值的效果,展望了今后的研究重点和方向.%Spiauterite-ZnO is a kind of high temperature thermoelectric material with excellent proper-ties, which has broad application in the space shuttle and solar-thermal electric power generation. The key problem of TE materials research is how to fully improve the thermoelectric figure of merit (ZT). The promis-ing value of ZT can be achieved by the integrated control of the transport properties of electron and phonon in order to achieve the coordination of thermal and electronic properties of materials. Recent research progress of thermoelectric properties of spiauterite-ZnO based TE materials in different dimensions, such as ceramics and nanostructures are reviewed. The optimizing effects by research method, doping and quantum confinement on electronic and phonon transport are analyzed, the effects on the enhancement of ZT value are discussed, and prospects for future research focus and direction are also included.
