A05 — Linking structure and collective excitations of mol2Dmat heterostructures by fast electrons
Principal Investigators: Dr. Benedikt Haas & Prof. Dr. Christoph Koch
Located at: Humboldt Universität zu Berlin
Project A05 uses high-resolution electron microscopy and spectroscopy to study mol2Dmat structures and their exciton-polaritons. It visualizes new molecular species, maps polariton behavior, and explores light–matter interactions. Advanced techniques, such as ptychography and laser-stimulated spectroscopy enable atomically resolved imaging of electrostatic potentials and selective spectroscopy of excited states.
Experimental methods: electron energy-loss spectroscopy (EELS), stimulated electron energy-gain spectroscopy (sEEGS), ptychography
