Abstract
Mixed oxides of the type Ln2(V3+4/3W6+2/3)O7, Ln=Gd---Lu, Y have been synthesized in vacuum via solid state reactions of the constituent oxides at 1150-1300°C. The compounds, which crystallize in cubic pyrochlore structure (α ~ 10.2 Å), have been characterized by X-ray, density and wet chemical analysis. Electrical resistivity and Seebeck coefficient measurements show the phases to be p-type extrinsic semiconductors with low energies of activation possibly exhibiting hopping-type behavior.
