Double-filled Ce0.6Yb0.4Fe3CoSnxSb12-x (x=0.1 - 0.4) skutterudite compositions were designed for enhanced thermoelectric properties. We fabricated the skutterudite specimens by using a melt-spinning process with subsequent a spark plasma sintering (SPS). Effect of Sn doping amount on the thermoelectric characteristics of the Ce0.6Yb0.4Fe3CoSnxSb12-x system were investigated. Single phase formation was examined by a XRD (X-ray diffraction) method. The microstructure was investigated by SEM (scanning electron microscope). The carrier concentration and carrier mobility were also measured to analysis the Sn doping amount effects on formation of the single phase and their properties in detail.
