Welcome to the pages of our research group!

We investigate quasiparticle, spin and valley dynamics in semiconductor quantum structures with a focus on transition metal dichalcogenides such as MoS?, MoSe?, WS?, WSe? and their van der Waals heterostructures. We use time- and spatially-resolved Kerr and Faraday rotation, time-resolved photoluminescence and Raman spectroscopy, which are usually carried out at low temperatures and, if necessary, under high magnetic fields. Van der Waals materials offer unique design possibilities due to their freely selectable orientation, targeted stackability of atomically thin layers and the development of new functionalities. Our aim is to elucidate the underlying mechanisms of spin, valley, and charge dynamics in these two-dimensional systems, for example, and thus lay the foundation for future applications in quantum technology and spintronics.
