Elevation of the Power Factor of Co 4 Sb 12 Skutterudite with Sm-Doping in High-Pressure High-Temperature Synthesis
Year: 2010
Type: article
Abstract: A thermoelectric material Sm x Co 4 Sb 12 (0 < x < 1.0) is synthesized at high pressure and high temperature leading to an enhanced power factor. The experimental measurements show that the Sm x Co 4 Sb 12 compounds exhibits n-type conduction. The absolute value of the Seebeck coefficient decreases with increasing Sm fraction. The resistivity increases with samarium content x from 0.1 to 0.2, but decreases dramatically when x changes from 0.2 to 1.0. The maximum power factor reaches 13.1 μW·cm −1 K −2 at x = 1.0, which is larger than the data previously reported for the La-doped CoSb 3 prepared at room pressure.
