Method of fabricating thermoelectric material and thermoelectric material fabricated thereby

Abstract

The object of the present invention is to provide a method of fabricating a thermoelectric material and a thermoelectric material fabricated thereby. According to the present invention, since carbon nanotubes with no surface treatment are dispersed in the alloy, electrical resistivity decreases and electrical conductivity increases in comparison to surface-treated carbon nanotubes and an amount of thermal conductivity decreased is the same as that in the case of using surface-treated carbon nanotubes, and thus, a ZT value, a thermoelectric figure of merit, is improved. A separate reducing agent is not used and an organic solvent having reducing powder is used to improve economic factors related to material costs and process steps, and carbon nanotubes may be dispersed in the thermoelectric material without mechanical milling.
