Fabrication of one-dimensional Cu2Te/Te nanorod composites and their enhanced thermoelectric properties

Abstract

Cu2Te/Te nanorod composite were fabricated and their thermoelectric properties were investigated. The composites were prepared by simple mixing of two different types of nanorods, which were synthesized by the solution mixing with PVP. The thermoelectric power factor of the Cu2Te/Te nanorod composite at room temperature was the highest (430.58 μV/K) at 10 wt.% Te. The enhancement in power factor is indicated by the change in electrical conductivity and Seebeck coefficient. Additionally, the composite has a 1D nanostructure, which can greatly reduce the total thermal conductivity of the composite owing to the strong phonon scattering effect. Because of the enhancement in power factor and decrease in thermal conductivity, the composite sample shows an enhanced thermoelectric figure of merit (ZT). The maximum ZT of the Cu2Te/Te nanorod composite was 0.22, which was achieved for a Te content of 10 wt.% and was ~ 4.5 times larger than that of the pristine Cu2Te nanorods.
