Abstract

Electrical conductivity measurements between 90 and 900°K have been performed on single crystals with composition UO_2.000 - UO_2.007. The activation energy decreases from 0.34 to 0.19 eV with increasing excess oxygen content. Hall effect measurements have yielded no measurable response (Hall mobility μ_H < 0.015 cm² V^-1 sec^-1 at 300°K). The results can be interpreted on the basis of small polaron theory.
