Abstract

original image

Alloys of AgSbTe2 and either PbTe or GeTe are the most efficient thermoelectric materials usable for power generation. Here two promising compositions for AgSbTe2–SnTe alloys (as shown in an ampoule in the figure) are identified where optimal p-type thermoelectric could be prepared that avoid issues with the cost of Ge or the negative perception of Pb salts.
