Abstract A thermoelectric material SmxCo4Sb12 (0<x≤1.0)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-1K-2 at x=1.0, which is larger than the data previously reported for the La-doped CoSb3 prepared at room pressure.
