Ternary thermoelectric material containing nanoparticles and process for producing the same

摘要

A thermoelectric material that comprises a ternary main group matrix material and nano-particles and/or nano-inclusions of a Group 2 or Group 12 metal oxide dispersed therein. A process for making the thermoelectric material that includes reacting a reduced metal precursor with an oxidized metal precursor in the presence of nanoparticles.
