Sn-FILLED AND Te-DOPED SKUTTERUDITE THERMOELECTRIC MATERIAL AND METHOD FOR MANUFACTURING THE SAME

摘要

A Sn-filled and Te-doped skutterudite thermoelectric material and method for manufacturing the same is provided to increase thermal conductivity by optimizing the concentration of a carrier. An Sn-filled and Te-doped skutterudite thermoelectric material is comprised of the steps: inserting cobalt, antimony, indium, and tellurium into the quartz tube; heating and melting the inserted material with high frequency induction power; rapidly freezing in the water in order to prevent formation of the second phase after melting; perform vacuum heating treatment to fill indium into the aperture and activate Te.
