| Abstract: | The temperature dependence of electrical conductivity in UO2+x has been measured in the temperature range 800–1340 K. It is suggested that an electrical current is carried by positive holes in the 2p band of oxygen, produced by the transfer of electrons to the vacant 5f band in U+5 ions associated with defect complexes. |
