-      \item C-C, 0.15 nm: NN-Abstand in Graphit bzw. Diamant\\
-            $\Rightarrow$ Formation of strong C-C bonds
-                          (almost only for high C concentrations)
-      \item Si-C, 0.19 nm: NN-Abstand in 3C-SiC
-      \item C-C, 0.31 nm: C-C Abstand in 3C-SiC\\
-            (vekettetrkettete, verschieden orientierte 100 C-Si Dumbbells)
-      \item Si-Si shows non-zero g(r) values around 0.31 nm like in 3C-SiC\\
-            and a decrease at regular distances\\
-            (no clear peak,
-             interval of enhanced g(r) corresponds to C-C peak width)

-            The <100> dumbbell configuration
-            \begin{itemize}
-              \item is identified to stretch the Si-Si next neighbour distance
-                    to 0.3 nm
-              \item is identified to contribute to the Si-C peak at 0.19 nm
-              \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
-            \end{itemize}
-            $\Rightarrow$ Start of amorphous SiC-like phase formation\\
-            $\Rightarrow$ Higher temperatures required for proper SiC formation
