Point Defect Structure of Chromium (III) Oxidequilibrium oxygen pressure, it changes to an n-type semiconductor with electrons and chromium interstitials dominant. The equilibrium constants associated with the formation of different defects are also obtained.

Electronic Structure of Transition Metal Impurities and of Surface Defects in SrTiO3ted and the corresponding binding energy estimated from the calculation. The same method has been applied to the surface defects (oxygen vacancy and Ti adatoms) in connection with photoemission experiments.

Interface Transport in Monoxidesed cation diffusion (αD′ δ/D ≈ 10.). It was not possible to confirm these results on bicrystals, where αD′ δ/D was found to be less than 10.. In our opinion, these controversial results are due to oxide scale artifacts.

Computer Simulation Studies of Fe1-xO and Mn1-xOgregate. We also show that inter-defect interactions will favour the formation of defect clusters. Lastly, we use the mass-action method to show how the slightly higher binding energies of clusters in Fe.O, may account for the difference in behaviour of the two oxides.

Thermodynamic and Structural Evidence for the Presence of Defect Clusters in Some Non-Stoichiometrict structures obtained in this way. Furthermore evidence from statistical thermodynamic calculations and from structural studies (X-ray and neutron scattering) for the existence of these tetrahedral defects in non-stoichiometric fluorite oxides are presented.
