Facile fabrication of one-dimensional Te/Cu₂Te nanorod composites with improved thermoelectric power factor and low thermal conductivity.

ABSTRACT: In this study, Te/Cu₂Te nanorod composites were synthesized using various properties of Cu₂Te, and their thermoelectric properties were investigated. The nanorods were synthesized through a solution phase mixing process, using polyvinylpyrrolidone (PVP). With increasing Cu₂Te content, the composites exhibited a reduced Seebeck coefficient and enhanced electrical conductivity. These characteristic changes were due to the high electrical conductivity and low Seebeck coefficient of Cu₂Te. The composite containing 30 wt.% of Cu₂Te nanorods showed the maximum power factor (524.6 μV/K at room temperature). The two types of nanorods were assembled into a 1D nanostructure, and with this structure, thermal conductivity decreased owing to the st
