Electronic Conduction in Single Crystals of Uranium Dioxide
Journal Article

· Journal of Applied Physics
Electrical conductivity measurements between 90 and 800 deg K were performed on single crystals of uranium dioxide with compositions in the range UO/ sub 2.000/ to UO/sub 2.007/. The activation energy calculated from the ln sigma T vs 1/T curves decreases from 0.34 to 0.19 ev with increasing excess oxygen content. Hall effect measurements by d-c and a-c techniques yielded no measurable response, and indicate that the Hall mobility is smaller than 0.015 cm/ sup 2/v/sup -1/ sec/sup -1/ at room temperature. This result and a consideration of the fundamental parameters determining the transport mechanism suggest an interpretation based on small polaron theory.
