Abstract:
The tellurium-containing cationic type-I clathrate Ge30P16Te8 was synthesized and its thermoelectric properties were investigated. This clathrate showed a p-type conductivity, while most of the clathrates are n type. The Ge30P16Te8 clathrate had a band gap energy of 0.62eV and a room temperature thermal conductivity of 9mWcm−1K−1, which is as low as those of germanium clathrates such as anionic Sr8Ga16Ge30 and cationic Ge38Sb8I8. The electronic structure of the Ge30P16Te8 clathrate was also calculated using an ab initio method.
