Liu, Wei-Di and Yang, Lei and Chen, Zhi-Gang ORCID: https://orcid.org/0000-0002-9309-7993 (2020) Cu2Se thermoelectrics: property, methodology, and device. Nano Today, 35:100938. pp. 1-24. ISSN 1748-0132


Abstract

In the last decade, high-performance Cu2Se thermoelectric materials and devices are attracting increasing research interest. In this review, we firstly summarize fundamentals of Cu2Se, including crystal structure, band structure, phase transition, and intrinsic thermoelectric performance. Then, we compare and overview the effectiveness of enhancing electrical transports and reducing lattice thermal conductivity on boosting figure of merit, zT of Cu2Se and found that zT enhancement of Cu2Se should be mainly attributed to reduced lattice thermal conductivity. After that, we highlight the chemical stability and mechanical properties of Cu2Se and its thermoelectric modules. In the end, we point out future research directions in the field of Cu2Se thermoelectrics. This review fills the gap of overview on the progress and challenge of Cu2Se thermoelectrics, and provide a new perspective to achieve Cu2Se-based thermoelectric materials with high thermoelectric performance.
