+First of all, I would like to thank my official advisors Prof. Dr. Bernd Stritzker and Prof. Dr. Kai Nordlund for accepting me as a doctoral candidate at their chairs at the University of Augsburg and the University of Helsinki.
+I am gratefull to Prof. Dr. Bernd Stritzker who, although being an experimental scientist, gave me the opportunity to work on a rather theoretical field.
+The working environment providing insight on problems dealt with in this thesis from the point of view of an experimentalist were of great importance contributing to the success of this work.
+Furthermore, I would like to thank Prof. Dr. Kai Nordlund for his expertise in the field of atomistic simulations and the possibility to repeatedly visit his group in Helsinki.
+Much progress of this study is owed to the regrettably few but fruitful discussions and explanations by electronic mail, within short meetings on conferences and, of course, during my long-term stays in the nice capital of Finland.
