TUD Dresden University of Technology, recognized as a University of Excellence, is a leading research institution in Germany with a global orientation and a strong regional presence. The university is committed to addressing the grand challenges of the 21st century through innovative research and interdisciplinary collaboration. The Cluster of Excellence “Responsible Electronics in the Climate Change Era (REC²)” is dedicated to developing sustainable solutions for the future of electronics, focusing on reducing resource and energy consumption and minimizing electronic waste. This PhD position is offered at the Faculty of Physics, Institute of Applied Physics, Chair of Ultrafast Microscopy and Photonics, under the supervision of Prof. Alexey Chernikov. The research will center on the optical and electronic properties of novel two-dimensional materials combined with quantum dot nanostructures. Key activities include spectroscopic investigations of two-dimensional semiconductors, advanced microscopy and time-resolved spectroscopy, testing the reusability of heterostructures, and exploring dielectric engineering concepts. The project also involves collaboration with sustainability experts and acquiring tools for life-cycle and sustainability analysis. Research at the Chair of Ultrafast Microscopy and Photonics is internationally recognized, focusing on many-particle effects and light-matter interactions in solid-state systems. The group is part of cutting-edge projects on exciton-electron complexes in atomically-thin semiconductors and quantum gases in moiré-ordered and reconstructed heterostructures. The position offers opportunities for collaboration with national and international partners, and results are expected to be communicated in peer-reviewed journals and at international conferences. Applicants should hold a master’s degree (or equivalent) in physics and possess strong experimental skills in optics and material preparation. Familiarity with low-dimensional van der Waals materials, spectroscopy, microscopy, strain engineering, and hybrid heterostructures is required. Excellent English language skills are essential. The university values diversity and encourages applications from women and candidates with disabilities. The position is remunerated according to salary group E 13 TV-L (75% of full-time weekly hours) for three years, with the possibility of extension. Additional benefits include access to state-of-the-art research facilities, the possibility to apply for GreenRiskFunds for high-risk/high-gain research ideas, international exchange opportunities, and a family-friendly work environment. PhD students benefit from a dual supervision concept, a structured PhD project plan, and mentorship via the REC² mentoring board and Thesis Advisory Committee. Applications should be submitted by December 11, 2025, as a single PDF file via the TUD SecureMail Portal or by email to Prof. Alexey Chernikov.
