Bulk nanocomposite thermoelectric materials nanocomposite thermoelectric materials powder and method for manufacturing the same

摘要

According to one aspect of the present invention, a plurality of thermoelectric material grains; And a nano metal layer crystallized from an amorphous metal having a glass transition temperature and a crystallization temperature lower than a melting point of the thermoelectric material at a grain boundary of the thermoelectric material; Lt; RTI ID = 0.0 nanocomposite thermoelectric / RTI By introducing the metal nano-layer at the boundary of the thermoelectric material grain, the quantum confinement effect and the PGEC concept can be realized in the bulk material, so that the thermoelectric material powder and the bulk thermoelectric material having high thermoelectric performance can be formed.
