WebCharge-state transition levels can be calculated with good accuracy from defect formation energies.25–29The latter can be obtained from density functional theory (DFT) as formation energy is a ground-state property. Empirical rules of thumb are available to localize the impurity levels of metal ions in dielectric hosts. Weblocating charge transition levels in the band gap, be-cause of the well known band gap problem from which they suffer. As a result, a direct comparison between calculated and experimental energy levels remains am-biguous. Furthermore, the determination of equilibrium densities of intrinsic defects and charge carriers is hin-dered [2].
