The thermoelectric and thermodynamic properties of polycrystalline InxCo4Sb12(0.0 ≤ x ≤ 0.26) skutterudites were investigated and analysed between 2 and 800K by means of electrical resistivity, thermopower, thermal conductivity and specific heat measurements.Hall effect, sound velocity and thermal expansion measurements were also made in order to gain insights into the transport and elastic properties of these compounds. The impact of the In filling on the crystal structure as well as the thermal dynamics of the In atoms were tracked down to 4K using powder neutron diffraction experiments. Analyses of the transport data were compared with the evolution of the electronic band structure with x determined theoretically within the Korringa–Kohn–Rostoker method with the coherent potential approximation.
