Sintering temperature dependence of thermoelectric performance in CuCrSe2 prepared via mechanical alloying

In this study, we successfully synthesized single phase of CuCrSe2 via mechanical alloying followed by annealing and spark plasma sintering. By optimizing the temperature of SPS, a maximum ZT value over 0.75 at 873 K is achieved in the completely pure sample sintered at 1023 K.158
