This has been shown to have two reasons, i.e. the overestimated barrier of migration due to the artificial interaction cut-off on the one hand, and on the other hand the lack of quantum-mechanical effects which are crucial in the problem under study.

%In order to get more insight on the SiC precipitation mechanism, further ab initio calculations are currently investigated.
