Abstract

The synthesis and chemical, structural and transport properties of [Ba.sub.8][Ga.sub.16][Si.sub.x][Ge.sub.30-x] type I clathrates with similar Ga-to-group IV element ratios but with increasing Si substitution are described. The results have described an additional method for tuning the electronic properties of [Ba.sub.8][Ga.sub.16][Ge.sub.30] for thermoelectric applications.
