Comparison of the size of the atom and the energy in 3d-impurities (a) the Goldschmidt radii (i.e., atomic radii)38 and covalent radii39 of the corresponding impurity in TiN (b) Migration barriers (\(E_m\)), formation energies (\(E^f\), \(E_{net}^f\)), and the activation energy (Q) for the vacancy-mediated process of all the impurities and that of interstitials of selected impurities.
