Reduction of thermal conductivity through nanostructuring enhances the thermoelectric figure of merit in Ge_1−xBi_xTe

Abstract

Nano/meso-structuring reduces the thermal conductivity in Ge_1−xBi_xTe samples, which results in a thermoelectric figure of merit, <italic>zT</italic>, of 1.3 in Ge_1−xBi_xTe.
