Abstract

In situ induced nanostructure is employed as an alternative way to enhance the thermoelectric performance of p-type CuInTe based thermoelectric materials in this work. Dispersive In O nanoparticles are formed in the samples with SnO by virtue of the in situ replacement of SnO and CuInTe . As a result, an obvious reduction in the thermal conductivity has been achieved due to the intensive scattering of phonon by the in situ formed In O nanoparticles. In addition, the power factor of CuInTe is less effected by SnO additive. Eventually, an enhanced ZT of 1.1 at 823 K has been achieved for the CuInTe –0.5% SnO sample. 2 2 3 2 2 2 2 3 2 2 2 2
