Thermoelectric Properties of the Clathrate I Ba8Ge433

The clathrate I Ba8Ge433 [space group \( Ia\bar{3}d \), no. 230, a = 21.307(1) Å] has been synthesized as a single phase and characterized by x-ray powder diffraction and metallographic analysis. Electrical and thermal transport measurements have been performed in the temperature range of 5 K to 673 K. Ba8Ge433 displays the electrical resistivity of a poor metal at low temperatures, with semiconducting-like behavior appearing above 300 K.
