Abstract:
A thermoelectric material has a microstructure deformed by cryogenic impact. When the cryogenic impact is applied to the thermoelectric material, defects are induced in the thermoelectric material, and such defects increase phonon scattering, which results in enhanced figure of merit.
Abstract:
A bulk thermoelectric material having a structure in which migration of carriers is not inhibited but phonons are scattered is described. The bulk thermoelectric material includes: a bulk crystalline thermoelectric material matrix; and nanoparticles coated with a conductive material within the thermoelectric material matrix.
Abstract:
A thermoelectric material including a thermoelectric matrix; and nano-inclusions in the thermoelectric matrix, the nano-inclusions having an average particle diameter of about 10 nanometers to about 30 nanometers.
