The processing parameter of sintering temperature is investigated in order to optimize the thermoelectric power factor of pressed Bi 0.5Sb 1.5Te 3 composites. As a result, we find that the composite sintered at 360 °C shows the best power factor performance among the composites and has a largest power factor of 15.4 μW/cm K 2 at 205 K and 13.5 μW/cm K 2 at 290 K. When compared with the samples without addition of carbon sphere in the hydrothermal synthesis, the composites sintered at 340 °C and 360 °C both surpass the largest power factor of 12.1 μW/cm K 2 at 280 K and 11.9 μW/cm K 2 at 290 K for the 340 °C-sintered counterpart.6enjournal article
