摘要

热电材料可以实现热能和电能的相互转换, 它是一种环境友好的功能性材料. 当前, 热电材料的热电转换效率低, 这严重制约了热电器件的大规模应用, 因此寻找更加优异热电性能的新材料或提高传统热电材料的热电性能成为热电研究的主题. 与块状材料相比, 薄膜具有二维的宏观性质和一维的纳米结构特性, 方便研究材料的物理机制与性能的关系, 还适用于制备可穿戴电子设备. 本文总结了Cu ₂Se薄膜5种不同的制备方法, 包括电化学沉积、热蒸发、旋涂、溅射以及脉冲激光沉积. 另外, 结合典型事例, 总结了薄膜的表征手段, 并从Cu ₂Se的电导率、塞贝克系数和热导率等参数出发, 讨论了各个参数对热电性能的影响机制. 最后介绍了Cu ₂Se薄膜热电的热门应用方向.

Abstract

Thermoelectric (TE) materials can directly realize the mutual conversion between heat and electricity, and it is an environmentally friendly functional material. At present, the thermoelectric conversion efficiencies of thermoelectric materials are low, which seriously restricts the large-scale application of thermoelectric devices. Therefore, finding new materials with better thermoelectric properties or improving the thermoelectric properties of traditional thermoelectric materials has become the subject of thermoelectric research. Thin film materials, compared with bulk materials, possess both the two-dimensional macroscopic properties and one-dimensional nanostructure characteristics, which makes it much easier to study the relationships between physical mechanisms and properties. Besides, thin film are also suitable for the preparation of wearable electronic devices. This article summarizes five different preparation methods of Cu ₂Se thin films, i.e. electrochemical deposition, thermal evaporation, spin coating, sputtering, and pulsed laser deposition. In addition, combing with typical examples, the characterization methods of the film are summarized, and the influence mechanism of each parameter on the thermoelectric performance from electrical conductivity, Seebeck coefficient and thermal conductivity is discussed. Finally, the hot application direction of Cu ₂Se thin film thermoelectrics is also introduced.
