-In another {\em ab inito} study Capaz et al. \cite{capaz94} determined this configuration as an intermediate saddle point structure of a possible migration path, which is \unit[2.1]{eV} higher than the \ci{} \hkl<1 0 0> DB structure.
-In calculations performed in this work the bond-centered configuration in fact is a real local minimum and an energy barrier is needed to reach this configuration starting from the \ci{} \hkl<1 0 0> DB configuration, which is discussed in section \ref{subsection:100mig}.
+In another {\em ab inito} study, Capaz~et~al. \cite{capaz94} in turn found BC configuration to be an intermediate saddle point structure of a possible migration path, which is \unit[2.1]{eV} higher than the \ci{} \hkl<1 0 0> DB structure.
+This is assumed to be due to the neglection of the electron spin in these calculations.
+Another {\textsc vasp} calculation without fully accounting for the electron spin results in the smearing of a single electron over two non-degenerate states for the BC configuration.
+This problem is resolved by spin polarized calculations resulting in a net spin of one accompanied by a reduction of the total energy by \unit[0.3]{eV} and the transformation into a metastable local minimum configuration.
+It is worth to note that all other listed configurations are not affected by spin polarization.
+However, in calculations performed in this work, which fully account for the spin of the electrons, the BC configuration in fact is a real local minimum and an energy barrier is needed to reach this configuration starting from the \ci{} \hkl<1 0 0> DB configuration.
+This is discussed in more detail in section \ref{subsection:100mig}.
+
+To conclude, discrepancies between the results from classical potential calculations and those obtained from first principles are observed.
+Within the classical potentials EA outperforms Tersoff and is, therefore, used for further studies.
+Both methods (EA and DFT) predict the \ci{} \hkl<1 0 0> DB configuration to be most stable.
+Also the remaining defects and their energetical order are described fairly well.
+It is thus concluded that, so far, modeling of the SiC precipitation by the EA potential might lead to trustable results.
