NANOCOMPOSITE THERMOELECTRIC CONVERSION MATERIAL AND PROCESS FOR PRODUCING SAME

摘要

The invention provides a nanocomposite thermoelectric conversion material (1) in which the matrix has a polycrystalline structure, and crystal grains (10) and a crystal grain boundary phase (12) of a different composition are present therein, and in which the same type of phonon-scattering particles (14) are dispersed within the crystal grains (10) and the crystal grain boundary phase (12).
