Nanocomposite thermoelectric conversion material, thermoelectric conversion element including the same, and method of producing nanocomposite thermoelectric conversion material

摘要

A nanocomposite thermoelectric conversion material includes a matrix of the thermoelectric conversion material; and a dispersed material that is dispersed in the matrix of the thermoelectric conversion material, and that is in a form of nanoparticles. Roughness of an interface between the matrix of the thermoelectric conversion material and the nanoparticles of the dispersed material is equal to or larger than 0.1 nm.
