Thermoelectric(TE)performance of polycrystalline stannous selenide(SnSe)has been remarkably promoted by the strategies of energy band,defect engineering,etc.However,due to the intrinsic insufficiencies of phonon scattering and carrier concentration,it is hard to simultaneously realize the regulations of ...
Here an effective strategy for enhancing the thermoelectric performance of p-type polycrystalline SnSe by Ag/Na dual-doping and Ag8SnSe6 (STSe) nanoprecipitates is reported. The Ag/Na dual-doping leads to a two orders of magnitude increase in carrier concentration and a convergence of valence ...
