Patent ID: 8865501

Claim:
A method of fabricating a thermoelectric material, the method comprising: preparing a colloidal solution having carbon nanotubes dispersed therein (step 1); adding a metal salt having thermoelectric properties to the colloidal solution prepared in step 1 (step 2); precipitating and growing an alloy on outer surfaces of the carbon nanotubes from the metal salt by a chemical reaction of the solution having the metal salt added thereto (step 3), wherein the carbon nanotubes with no surface treatment are used, wherein step 1 is performed by introducing carbon nanotubes with a surfactant into 1-dodecanethiol having reducing power, and wherein the chemical reaction in step 3 is performed at a temperature ranging from 100° C. to 150° C. for 1 hour to 3 hours.
