Abstract

We demonstrate that insulating-boron nanoparticle inclusion in Cu₂Se has little effect on the overall power factor, but can significantly reduce the thermal conductivity, resulting in great improvement on zT, by a factor of 1.6–2.6 compared to undoped Cu₂Se over a wide range of temperatures.
