摘要

We report on the synthesis and low temperature transport properties of rhombohedral derivatives of the cubic skutterudite CoSb_3, namely Co_(4-x)Fe_xGe_6Se_6 with x = 0, 1, 1.5. Rietveld refinement and elemental analyses were used to identify the structure and stoichiometry of the compositions. The thermal conductivity was investigated by employing the Debye model with different phonon-scattering parameters. This investigation demonstrates that Fe substitution is feasible in these skutterudite derivatives and can significantly affect the transport properties as compared with Co_4Ge_6Se_6.
