• I am grateful to Ms. A. Ehlers, who accompanied me many years from the first
steps in Marburg as an invaluable, precise, and warmhearted assistant in the Experimental Semiconductor Physics group. Her professional experience, which she
brought from Bosch into the research group previously led by Prof. W. Rühle,
made her retirement create a noticeable gap in our group’s administration. Also, I
would like to thank Ms. M. Strobel, assistant of the group, who had to balance her
time carefully between two locations in Marburg, for her administrative support
in processing numerous project related issues, such as staff employment and other
financial matters.
• Furthermore, I would like to thank Dr. G. Urbasch, Dr. B. Fischer and Dr. J.
Balzer for the helpful discussions and the collaborative work in the Experimental
Semiconductor Physics group, S. Sommer and N. Born from the Terahertz-part
of the group for the helpful discussions, and technician of the group R. Rink
for his constant help that enabled the smooth expansion and operation of various
pieces of lab equipment. Many thanks are devoted to the mechanical and electrical
workshops at the Department of Physics and their staff for their frequent help with
technical constructions and problem solving.
• I am grateful to faculty members Prof. em. G. Weiser and Prof. W. Heimbrodt
for enriching discussions on semiconductor optics and support in the field of
semiconductor spectroscopy, respectively. Prof. Weiser’s insightful talks, which
provided important views and pedagogical summaries on light–mater interactions
in organic and inorganic semiconductor systems, given in my team’s internal seminars have always been valued by my students and me. Moreover, I very much value
the occasional meetings we have had and his kind nature. With Prof. Weiser’s
encouragement and affirmations, I could easily follow my scientific instincts and
push forward my investigations, knowing that they are of interest to him as a
semiconductor expert. Also, I am thankful for his helpful improvement recommendations regarding my work’s summary (Sect. 8.1 in this book). Furthermore,
the fruitful cooperation with Prof. Heimbrodt, his benevolence, his lasting support
with regard to using his equipment, and the kind help of various of his team
members, particularly J. Kuhnert and M. Wilhelm, is acknowledged.
• I would also like to thank guest researchers Prof. G. Town, Dr. W. Lai, and many
others for the fruitful collaborations and scientific discussions, visiting Ph.D.
students R. Li, W. Kong, X. Lin, H. Zhu, H. Guoyu, H. Alaboz and visiting
scholars H. Keskin, D. Abdrabou for their commitment in the laboratories of the
group and the positive role in my teams. Similarly, I would like to thank visiting
DAAD Rise students D. Renaud, N. Wilson, C. McGinn for their help in the lab
and the Marburg group’s (former) Ph.D. students M. Drexler and C. Lammers,
who supported the DAAD Rise internship announcement as well as supervision,
and C. Lammers, D. Renaud, D. Berkhahn and G. Otto for their assistance during
my public ‘laser’ talks.
• Special thanks are devoted to Prof. H. Z. Wu from the Department of Physics and
the State Key Laboratory of Silicon Materials of the Zhejiang University (ZJU)
in Hangzhou, China, for hosting me in his group multiple times, for inviting me
to give numerous guest lectures, for the fruitful collaboration on nanomaterials
