The Copper Selenide, which exhibits a liquid-like behavior, shows superior electrical property and low thermal conductivity. It has a high zT at a phase transition temperature of 400 K. Herein, we prepared two series of Te-doped Cu2Se crystals, whose nominal compositions are Cu2Se1-xTex and Cu2-ySeTey, and their thermoelectric properties and phase transition are discussed. An isothermal section at 573 K of the ternary Cu-Se-Te is constructed based on the microstructural and compositional analysis. We further found that two ternary compounds are thermally stablized at 573 K.
