Interface engineering of luminescent defects in 2D materials
 (W07)

• Subject Area: Experimental Condensed Matter Physics ; Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas ; Theoretical Chemistry: Electronic Structure, Dynamics, Simulation
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 441234705

In project W07, we will encapsulate fluorescent molecules into Boron Nitride multilayers, at a sufficiently low density that single molecules can be observed in a diffraction-limited confocal microscope. We will perform low-temperature spectroscopy of the resulting systems, in the spirit of single-molecule experiments in organic matrices. These experiments will be supported by electronic structure theory and molecular dynamics simulations. The single emitters will finally be used as point sources in optical near-field microscopy, aiming to study Förster energy transfer into other systems of the CRC and beyond.
