Abstract

We report a facile and efficient way to enhance and modulate thermoelectric performance by incorporating chemically synthesized Cu ₂ Te nanoparticles on p-type Bi _0.5 Sb _1.5 Te ₃ matrix. By varying the amount of Cu ₂ Te nanoparticles, the temperature of maximum thermoelectric performance shifted systematically from room temperature to 425 K. The highest figure-of-merit value, 1.1, was achieved at 377 K by incorporating 0.1 wt% Cu ₂ Te nanoparticles in Bi _0.5 Sb _1.5 Te ₃ matrix, which is due to enhancement in power factor and reduction in lattice thermal conductivity. The results demonstrate that Cu ₂ Te incorporation could be an effective strategy for Bi-Te based thermoelectric power generation.
