Sm-substitution effects on structural and transport properties of PbSe

Polycrystalline single phase of Pb1−xSmxSe (x = 0.00–0.09) samples were prepared by the solid state reaction. XRD and SEM/EDAX methods were used for structural and chemical characterization of the obtained materials. The investigated samples were also characterized by the measurements of the samarium concentration dependence of the electrical conductivity and Seebeck coefficient. The power factor shows that these materials have the potential for high temperature applications with promising thermoelectric performance.
