Thermoelectric performance of Fe2VAl/CNT-based alloys
Abstract
<jats:p>Heusler-type Fe2VxTi 1-xAl alloys offer an alternative solution for thegeneration of thermoelectric power near room temperature. In the currentresearch, thermoelectric properties of the p-type Fe2V0.9Ti0.1Al andFe2V0.9Ti0.1Al/CNTs alloys, prepared by SPS, were studied. Carbon nanotubes(CNTs) were used as dopants to improve the Seebeck coefficient andelectrical conductivity. Upon doping with CNTs, the thermal conductivity wassignificantly reduced, meanwhile, the value of the power factor increasedfrom 0.45 to 1.55 mW/mK2 at around 330K. The effect of CNT inclusions on thethermoelectric parameters of Fe2VxTi 1-xAl compounds was systematicallystudied. When compared to Fe2V0.9Ti0.1Al, which had a figure of merit ofjust 0.02 at 330 K, the CNT-containing samples showed a significantlyimproved figure of merit up to 0.07. we offer a novel technique to improvethe performance of Fe2VAl alloys.</jats:p>
