Diploma - Max Planck Institute for Solid State Research

Acknowledgements
I am deeply grateful to Prof. C. Laubschat for the possibility to do my diploma thesis
in his research group. Particulary, I want to thank for the granted freedom to discover
the aspects of photoemission myself and having the chance to freely shape my work in
conjunction with invaluable discussions which motivated me to go further. Moreover,
I thank every member of the group for their support, especially Steffen Danzenbächer
and Denis Vyalikh for their valuable discussions and cheer-ups in times of struggling
problems.
I am grateful for the love, patience and balance which my girlfriend gave me. Her
support strengthens me to proceed my tasks. I apologize for my grumbling, nights spent
for work and late arrivals at evenings.
Additionally, I thank Yuri Kucherenko, Klaus Koepernik and Helge Rosner for valuable
hints on theoretical fundamentals and their patience in our discussions. Without
their theoretical support and knowledge, I would not have been able to write this thesis.
