+Figure \ref{fig:defects:comb_db_01} shows the structure of these two configurations.
+
+Structure b) is the energetically most favorable configuration.
+The two carbon atoms form a bond to each other.
+This suggests an unwanted C clustering in SiC production.
+However, for the second most favorable configuration, presented in figure a), the amount of possibilitie for this configuration is twice as high.
+Investigating C-Si and C-C bond lengths ...
