Stabilized copper selenide thermoelectric materials and methods of fabrication thereof
Abstract
A thermoelectric composition is provided that includes a nanocomposite comprising a copper selenide (Cu2Se) matrix having a plurality of nanoinclusions comprising copper metal selenide (CuMSe2) distributed therein. M may be selected from the group consisting of: indium (In), aluminum (Al), gallium (Ga), antimony (Sb), bismuth (Bi), and combinations thereof. The thermoelectric composition has an average figure of merit (ZT) of greater than or equal to about 1.5 at a temperature of less than or equal to about 850K (about 577° C.). Methods of making such a thermoelectric nanocomposite material by a sequential solid-state transformation of a CuSe2 precursor are also provided.
