+            \begin{itemize}
+              \item is identified to stretch the Si-Si next neighbour distance

+              \item explains further C-Si peaks (dashed vertical lines)
+            \end{itemize}
+            $\Rightarrow$ C atoms are first elements arranged at distances
+                          expected for 3C-SiC\\
+            $\Rightarrow$ C atoms pull the Si atoms into the right
+                          configuration at a later stage
+      \item High C concentration (i.e. $V_2$ and $V_3$):
+            \begin{itemize}
+              \item High amount of damage introduced into the system
+              \item Short range order observed but almost no long range order
