FIG. 1.

Temperature dependence of the electrical conductivity (a), thermopower (b), and thermal conductivity (c), and room temperature lattice thermal conductivity as a function of total filling fraction for skutterudites (d). The solid line is to guide eye. The lattice thermal conductivities of (×), (✫), (⊞), and (◇) from Ref. 18 are also shown. The solid line emphasizes the monotonic decrease in with increasing filling fraction .
