Abstract

Resistivity and thermopower data is presented on Eu-doped CoSb3 skutterudites over the temperature range of 10 K to 700 K. Thermal conductivity is also presented from 10 K to 300 K in order to determine the figure of merit. Eu0.43Co4Sb11.59Ge0.31 and Eu0.42Co4Sb11.37Ge0.50 exhibit an enhanced figure of merit as compared to CoSb3 and Eu0.2CoSb3. Data on a series of Yb-filled CoSb3 is underway and preliminary data is presented.
