A BiCuSeO system has been reported as a promising thermoelectric material and has attracted great attention in the thermoelectric community since 2010. Recently, several remarkable studies have been reported and the of BiCuSeO was pushed to a higher level. It motivates us to systematically summarize the recent reports on the BiCuSeO system. In this short review, we start with several attempts to optimize thermoelectric properties of BiCuSeO. Then, we introduce several opinions to explore the origins of low thermal conductivity for BiCuSeO. Several approaches to enhance thermoelectric performance are also summarized, including modulation doping, introducing dual-vacancies, and dual-doping, etc. At last, we propose some possible strategies for enhancing thermoelectric performance of BiCuSeO in future research.
BiCuSeO体系已被报道为一种很有前景的热电材料，自2010年以来在热电领域引起了极大关注。最近，已有几项引人注目的研究报道，BiCuSeO的性能被提升到了一个更高的水平。这促使我们系统地总结BiCuSeO体系的最新报道。在这篇简短的综述中，我们首先介绍了几种优化BiCuSeO热电性能的尝试。然后，我们介绍了几种探究BiCuSeO低热导率起源的观点。还总结了几种提高热电性能的方法，包括调制掺杂、引入双空位和双掺杂等。最后，我们提出了一些在未来研究中提高BiCuSeO热电性能的可能策略。
