CRC 951/3: Optical Excitations of TMDC/Dye Hybrids Under Mechanical Strain (SP A06)

The central goal of this project is the preparation and investigation of stable and efficient emitters, which are formed by incorporating single dye molecules into a transition metal dichalcogenide (TMDC) layer. The local deformations and associated strains within the TMDC are to be used to direct excitons from longer distances to the molecule and, thus, to increase the excitation efficiency. In addition to examining the optical transitions of the hybrid inorganic/organic system (HIOS), this study can also lead to the realization of novel quantum emitters in a 2D geometry that are bright, photostable, and tunable. Besides scanning probe microscopy, confocal and near-field optical excitation as well as detection at room temperature and at cryogenic temperatures are used for these investigations.
