Physical significance of the measured electric conductivity

The previous kinetic model has allowed us to show that the electric effects observed on nickel oxide were linked to the migration of the nickel ions in the network. Such a phenomenon implies that these ions can temporarily be found in interstitial sites, favoring the creation of an activated complex electrically neutral and near the conduction band of the oxide this proximity then favors an election transfer, given  

The electrons transferred by the conduction band have a short lifetime duration, at most the length of the complex life, and will thus ensure a permanent renewal of the material conductivity. In stationary condition, this effect will be permanent and 

The electric behavior of beta-alumina, both treated and not treated with sulfur dioxide, questions the interpretation of the phenomenon relative to the creation of a potential linked to the nature or the geometry of the electrodes, and linked to the nature of the gaseous atmosphere in which it is plimged.
