\chapter*{Acknowledgment}
\addcontentsline{toc}{chapter}{Acknowledgment}

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.

Due to the official supervising of both of them, participation in a special research fellowship of the Bayerische Forschungsstiftung was enabled providing financial support for the first three years.
Next to living costs, travel expenses for scientific conferences as well as my stays in Helsinki were unbureaucratically taken over by the research foundation.

I owe my deepest gratitude to Prof. Dr. J\"org K. N. Lindner guiding me through my first time of scientific working already beginning with the diploma thesis.
I am heartly thankful for his frequent encouragements and the confidence he has shown enabling a greatly independent research and the improvement of respective skills.
Furthermore, his experiences in the materials system covered in this study were of great help for this work.
