英文摘要	In this work, we demonstrate simultaneous enhancement of the power factor and thermoelectric performance of Cu2S upon the introduction of In2S3. The evident improvement in electrical conductivity, coupled with the less affected Seebeck coefficient, leads to a high power factor of 1361 mu Wm(-1) K-2 at 850 K, which is much higher than the previously reported values for Cu2S-based thermoelectric materials. Along with moderate thermal conductivity, a high ZT value of 1.23 at 850 K is achieved. Interestingly, the phase transitions and copper segregation of Cu2S are also suppressed by In2S3 doping due to the formation of the nanoscale CuInS2 phase. Such a high power factor, together with a decent ZT value and suppressed phase transitions and copper segregation, will be beneficial to its practical applications in thermoelectric power generation.
