High seebeck coefficient and low thermal conductivity in Bi and In co-doped GeTe thermoelectric material

Pure GeTe shows inferior thermoelectric performance due to the large carrier concentration caused by the intrinsic high concentration of Ge vacancies. In this study, we report improved thermoelectric performance of Bi and In co-doped GeTe based thermoelectric material where a figure of merit, ZT ∼ 1...
