+  C 100 interstitial migration along 110 in c-Si (Albe potential)\\
+ }
+
+ {\color{blue}New approach:}\\
+ Place interstitial carbon atom at the respective coordinates
+ into a perfect c-Si matrix!\\
+ {\color{red}Problem:}\\
+ Too high forces due to the small distance of the C atom to the Si
+ atom sharing the lattice site.\\
+ {\color{green}Solution:}
+ Slightly displace the Si atom\\
