Electrical conductivity in nonstoichiometric cobalt monoxide a Monte Carlo simulation

Abstract The predictions of a recently published model, taking into account the influence of long range Coulomb interactions, have been tested on a typical non stoichiometric transition monoxide, the cobalt monoxide. As predicted by the model, the published experimental results are consistent with a decrease of electronic mobility and an increase of activation energy as the departure from stoichiometry increases. The phenomenological dielectric constant calculated from purely thermodynamic analysis allows to obtain a quantitative agreement with experimental results.
