Abstract

The effect of Ni doping on both electron and phonon transport properties of nanostructured CoSbS has been investigated in this study. We found a more than 2 times increase on figure-of-merit (ZT). The noticeable enhancement is mainly attributed to the optimized carrier concentration, high effective mass and strong electron-phonon scattering upon Ni doping. A ZT of 0.5 was achieved at 873 K together with a power factor of 20 μW cm^-1 K^-2 for the Ni doped CoSbS samples. The reduced lattice thermal conductivity via the strong electron-phonon scattering for Ni doped CoSbS samples is confirmed by the quantitative calculation of the various phonon scattering mechanisms according to the Callaway model.
