NANOCOMPOSITE THERMOELECTRIC CONVERSION MATERIAL, THERMOELECTRIC CONVERSION ELEMENT INCLUDING THE SAME, AND METHOD OF PRODUCING NANOCOMPOSITE THERMOELECTRIC CONVERSION MATERIAL

摘要

A nanocomposite thermoelectric conversionmaterial includes a matrix of the thermoelectric conversionmaterial; and a dispersed material that is dispersed in thematrix of the thermoelectric conversion material, and that isin a form of nanoparticles. Roughness of an interfacebetween the matrix of the thermoelectric conversion materialand the nanoparticles of the dispersed material is equal toor larger than 0.1 nm.
