Progress of research on high entropy thermoelectric materials
High-entropy alloys have excellent properties such as high strength,high hardness and oxi-dation resistance,making them widely used in various fields.With the extensive application of high-entropy alloys,the design of multi-principal element compositions to increase the configurational entropy and exploit the properties of high-entropy alloys has also been used to control the performance of thermoelectric materials.This article reviews the current development status of common high-entropy thermoelectric materials and analy-ses the prospects of decoupling the effect of entropy on thermoelectric performance.By analysing the applica-tion of entropy engineering in thermoelectric materials such as Ⅳ-Ⅵ group materials,liquid-like materials,half-Heusler alloys,etc,the influence of high entropy on thermoelectric performance is summarised.Through alloying,high entropy effects,liquid-like effects,solid solution amount,resonance doping,nanoprecipitation,and the construction of adaptive sublattices,the performance of thermoelectric materials can be significantly improved,opening up new directions for the development of more efficient thermoelectric conversion materials.
