PHOTONICS IN 2D-MATERIALS
BMBF Junior Research Group on
Photonics in 2D-Materials
The Junior Research Group Photonics in 2D-Materials is dedicated to the understanding of light-matter-interaction in atomically thin layers of nanomaterials, to the tailoring of their optical response on the femtosecond scale, and to leverage their properties for applications in Photonics. Some examples for these materials are transition-metal dichalcogenides (TMDs) and hexagonal Boron-Nitride (hBN), which naturally form mono-molecular and semiconducting sheets thinner than a nanometer but with an enormous degree of optical activity.
TMDs exhibit complex and sometimes non-intuitive behaviour. This is related to their internal dynamics, e.g. the formation and decay of excitonic states, as well as to their interaction with the environment on the nano-scale, or to the behaviour of electronic excitations at edges and boundaries. These interactions shape the optical response. They dominate optical properties, such as transmission, fluorescence, single-photon emission, nonlinearity, or strong coupling with resonances. Our research aims to fully characterize and understand these interactions, both on the nanoscale, as well as, in terms of the resulting optical properties.
Their extreme electro-optical properties and miniscule size make them ideal workhorses for fundamental investigations into new modes of optical sensing, nanoscale quantum-photonic light sources, and for the integration with micro- and nanooptical components. We aim to explore fundamental properties of these materials, investigate fabrication routes, and demonstrate their usage for real-world application scenarios.
