We report the synthesis of Cu substituted Mn1−xCuxSb2Se4 and its interesting resonant doping behavior, leading to zT of 0.64 at 773 K for the Mn0.75Cu0.25Sb2Se4. Cu-doped MnSb2Se4 could be considered as a new platform for power generation.

Properties Of Materials

Cu doped Bi1.5Pb0.5Sr1.8La0.2Co2-xCuxOy(x = 0.0, 0.2, 0.4) samples were prepared through the solid state reaction method. The influence of different Cu doping contents on electrical resistivity, Seebeck coefficients, thermal conductivity, and the dimensionless figure of meritZTwas investigated. All the samples of Cu concentration 0.4 are single phases. The electrical resistivity of Bi1.5Pb0.5Sr1.8La0.2Co1.8Cu0.2Oydescends, and itsZTvalues are enhanced obviously. The results show that suitable element doping can modify the electric transport properties and enhance thermoelectric properties of materials.
