Abstract(#br)SnTe, a Pb-free analogue of PbTe, was earlier assumed to be a poor thermoelectric material due to excess p -type carrier concentration and large energy separation between light and heavy hole valence bands. Here, we report the enhancement of the thermoelectric performance of p -type SnT...
