Entropy engineering in CaZn2Sb2-YbMg2Sb2 Zintl alloys for enhanced thermoelectric performance
文献摘要：
The significant atomic disorder induced by entropy engi-neering can effectively suppress lattice thermal conductivity and improve thermoelectric performance.The variety of compositions of Zintl phases offers a wide range of possibil-ities for entropy engineering.Herein we successfully prepared a five-component solid solution(CaZn2Sb2)0.5(YbMg2Sb2)0.5 with a configurational entropy of～1.40R,where R is the gas constant.As a result,the room-temperature lattice thermal conductivity was only～0.68W·m-1·K-1,which is lower than that of all AM2Sb2 Zintl phases.Moreover,combined with the optimization of the carrier concentration by Ag doping at M site of AM2Sb2,a peak figure of merit(zT)value of～1.17 was achieved at 773 K for(CaZn1.997Ag0.003 Sb2)0.5(YbMg1.997Ag0.003Sb2)0.5.
