Cooperative regulation of electrical and thermal transport behavior enhancing the thermoelectric performance of SnTe

SnTe is a kind of promising candidates for medium temperature thermoelectric materials, while its thermoelectric properties are limited by not only the poor electrical transport properties caused by intrinsic high carrier concentration and large valence bands offset, but also the relatively high lattice thermal conductivity. In this work, the thermoelectric performance of Mn–Bi and Mn–Sb co-doped SnTe is investigated. As expected, Mn doping...
