摘要：

Enhanced electrical transport and ultra low thermal conductivity resulted in a high thermoelectric figure of merit, ZT, of similar to 1 and similar to 1.15 at similar to 680 K in 4 mol% Pb and 2 mol% Bi doped AgSbSe2, which are 150 and 190% higher compared to that of the pristine sample, respectively. With this excellent thermoelectric performance, p-type AgSbSe2, constituting earth abundant Se, offers promise to replace traditional metal tellurides containing expensive and scarce Te for mid temperature (350-700 K) thermoelectric applications.
