Abstract
- Single-crystalline samples of type-VIII clathrate [Ba.sub.8][Ga.sub.16-x][Al.sub.x][Sn.sub.30] are grown from Sn flux to analyze the structural and thermoelectric properties from 300 to 600 K. The Seebeck coefficients of all samples are largely negative and the large thermopower has coexisted with the metallic behavior in the electrical resistivity.
