TUD Dresden University of Technology, recognized as a University of Excellence, is a leading research institution in Germany with a global reputation for innovation and interdisciplinary collaboration. The Faculty of Physics, Institute of Applied Physics, and the Chair of Ultrafast Microscopy and Photonics invite applications for a PhD position focused on the ultrafast detection of THz-controlled light emitters in quantum matter. This research associate role is part of cutting-edge projects investigating many-particle effects and light-matter interactions in solid-state systems, with particular emphasis on two-dimensional semiconductors and quantum gases in moiré-ordered and reconstructed heterostructures. The successful candidate will join a highly motivated, international team working at the forefront of optoelectronics and novel semiconductor research. The position involves scientific research on the optical properties of excitonic many-particle states in advanced two-dimensional materials coupled to THz radiation. Key tasks include spectroscopic investigations, measurements and analysis using both linear and non-linear microscopy, and the integration of optical and THz excitation techniques with streak camera detectors. The role also offers opportunities for collaboration with national and international research partners and for presenting results in peer-reviewed journals and at international conferences. This position is funded by the Federal Ministry of Education and Research (BMBF) and is remunerated according to salary group E13 TV-L, at 75% of full-time weekly hours. The initial contract runs until June 30, 2028, with the possibility of extension. The employment period is governed by the Fixed Term Research Contracts Act (WissZeitVG), and the position provides an excellent opportunity for further academic qualification. Applicants should hold a master's degree (or equivalent) in physics and demonstrate strong motivation for both fundamental and applied research. Essential skills include experimental expertise in optics and material preparation, familiarity with low-dimensional van der Waals materials, up-to-date knowledge of spectroscopy and microscopy, and experience with strain engineering and hybrid heterostructures. Proficiency in English is required. TUD Dresden is committed to diversity and encourages applications from women and individuals with disabilities. The university is certified as family-friendly and offers a supportive working environment. To apply, submit your detailed application as a single PDF file by November 26, 2025, preferably via the TUD SecureMail Portal or by email to Prof. Alexey Chernikov.
