The Department of Mathematics and Natural Science, in Institute for Physics, Fundamentals of energy materials offers a job position of a

Ph. D. student (f/m/d)

The department is one of the leading groups in the analysis of semiconductor interfaces and the develop-ment of a low-defect integration of high-performance III-V compound semiconductors with low-cost Si substrates for highly efficient solar energy and solar-to-hydrogen conversion. The position is part of a project in which III-V heterostructures are prepared by metalorganic vapor deposition and characterized in terms of their atomic and electronic III-V/III-V as well as water/III-V interface structure for efficient direct solar-driven water photo-electrolysis. To this end, we offer a unique infrastructure that includes epitaxy, in-situ spectroscopy, and in-vacuo analytics (such as STM, FTIR, LEED, and UPS/XPS) located in a high-end cleanroom. We offer international group and a teamwork environment. The department is a member of the cross-faculty Institute of Micro- and Nanotechnologies offering further sophisticated analytics equipment and expertise. The funding will support participation at national and international conferences and gives opportunity to build well-established bridges between research groups in Darmstadt and Berlin. Active participation of the Ph.D. student in teaching is desired.
Besides its excellent campus, Ilmenau is a small, vivid, and affordable student city. Located virtually in the center of Germany with a direct connection to Erfurt. It is surrounded by the beautiful nature of the “Thüringer Wald” being famous for outdoor activities.
