• A pleasant return to the subject of my Master thesis in combination with my
works on VECSELs with the result of a record-high single-photon flux became
feasible thanks to the effective and straightforward cooperation with Prof. S.
Reitzenstein, Dr. T. Heindel, A. Schlehahn, and co-workers, and the enthusiasm
of team members M. A. Gaafar and M. Vaupel from Marburg.
• I am grateful to Dr. S. L. Tait and Prof. K. Kern from the Max Planck Institute for
Solid State Research, Stuttgart, Germany, for having laid the foundations of my
nanomaterials research with their supervision of my Bachelor project on scanningtunnelling microscopy and organic molecules on copper crystal surfaces long time
ago, and Prof. J. Geurtz in Würzburg for having promoted semiconductor physics
at an early stage.
• Financial support by the Federal Ministry of Education and Research (BMBF)
in the frame of the German Academic Exchange Service’s (DAAD) program
Strategic Partnerships and Thematic Networks is acknowledged, which provided
me the means to frequently visit the Zhejiang University in Hangzhou, China,
for course teachings of Master students at the Department of Physics, for the
establishment of research collaborations with different groups as well as joint
lecture courses for senior Bachelor students at the Department of Optical Science
and Engineering. I would also like to thank the International Office in Marburg,
particularly Ms. S. Halliday, for administrative support on this matter.
• Multiple fellowships by the German Academic Exchange Service (Deutscher
Akademischer Austausch Dienst, DAAD) and the German National Academic
Foundation (Studienstiftung des Deutschen Volkes) during all phases of my
personal academic development helped to obtain the necessary flexibility,
mobility, and freedoms for continuous progress in the domain of science.
• A scholarship from the Adolf-Häuser Stiftung for a short-term visit to the Aston
University is acknowledged which provided an important link to long-term cooperation partners and facilitated the establishment of collaborative work with the
group of Prof. E. U. Rafailov.
• Financial support by the Deutsche Forschungsgemeinschaft (DFG) for my
completed, prolonged and current projects via DFG grants RA2841/1-1,
RA2841/1-3 (“Investigating Self-Mode-Locking in Semiconductor Disk Lasers”),
RA2841/5-1 (“Theoretical and experimental study of optical properties of 2D
material heterostructures”, collaborative Marburg–Berlin 2D heterostructures
research), and RA2841/9-1 (“Manipulation and Control of Coherent States in
Exciton–Polariton Systems (MacExP)”, collaborative Marburg–Lecce exciton–
polariton research) is acknowledged. I am thankful to the DFG for having enabled
me to perform independent and self-determined scientific work.
• Financial support by the Philipps-Universität Marburg via the Forschungsförderfond is acknowledged, which provided seed funding for my young-group-leader
project “Heterostructures and Interfaces in Two-Dimensional Material Systems”
with the aim of an expansion of 2D-materials research.
• Financial support by the DFG SFB1083 “Structure and Dynamics of Internal
Interfaces” is acknowledged, which enabled the expansion of a microphotoluminescence setup for 2D-materials research.
