Abstract

The partially filled skutterudite structure is a candidate thermoelectric material with the capacity for phonon scattering by the decoupled rattling of filling ions. In this transmission electron microscopy investigation of a 1.6%Ce, 1.6%Ni, 4.9%Ge, 22.8%Co, and 69.1%Sb alloy, the structure is found to be that expected of a partially-filled skutterudite, but with a varied assortment of structural defects. These defects are characterized and their effect on thermoelectric properties is discussed.
