Acknowledgments At this point, I want to acknowledge all those who helped me during this work, including the ones I will forget to include in this list: First of all, I would like to express my gratitude to Prof. Lux-Steiner for the great interest in my work and for all the discussions and suggestions to my thesis. I would also like to thank Prof. Brewer for his interest in this work and for its revision. My particular thanks go to my supervisor Dr. Friedhelm Finger, for his attention and patience guiding my work from the very beginning till writing the manuscript. I gratefully acknowledge his support in the discussion of ideas and results as well as in the experiments, which largely contributed to the success of this work, and that made this time a real pleasure. I would also like to thank Prof. E.A. Schiff for giving me the opportunity to work in his lab at Syracuse University. For introducing me into the exciting field of transient photocurrent experiments, for all the enlightening discussions and all the suggestions concerning my thesis. Dr. Reinhard Carius I thank for his great interest into my work and all the discussions. Special thanks goes to Dr. Steve Reynolds, Torsten Bronner, Christoph Ross, Mar’yun Donna Kay Thame and Stefan Klein for carefully reading the manuscript. I would also like to thank all my friends from the physics subbasement at SU, as there are Steluta Dinca, Jian Jun Liang, Weining Wang and Kai Zhu. I’m also very grateful to Johannes Wolff, Silke Michel and Andreas Lambertz for the technical support. 137
138 Acknowledgments I’m very thankful to Markus Hülsback for providing the Raman data used in this work, Stefan Klein for preparing the HWCVD material, the numerous discussions and carefully reading the manuscript, Yaohua Mai, Andreas Lambertz, Gunnar Schöpe, Matthias Krause and Erke Bunte for preparing the excellent pin diodes used for TOF. I especially thank all my colleagues from the IPV. Last but not least, I want to express my deep gratitude to my girlfriend Dana Freese, my parents and my brother for their encouragement and support in various aspects. 138
