The experimental research group of Monika Fleischer has extensive experience in nano-technology. Current topics of research interest are the fabrication and optical analysis of metallic nanostructures for nano-optics / plasmonics, near-field microscopy and sensing. The group works in a clean-room environment using optical, electron beam, and ion beam lithography as well as alternative lithography processes, thin-film deposition, and wet and dry etching for the fabrication of nanoantennas with specially designed properties, such as e.g. nanocones. For their characterization scanning electron and helium ion microscopy are employed as well as angle-resolved extinction and dark-field microscopy and spectroscopy. The optical properties of individual nanostructures are determined by numerical simulations. Current research questions include the nonlinear optical properties of nanoantennas, the manipulation of the emission properties of nano-emitters in hybrid structures, the use of hotspots in variable nanogaps, or the integration of nanoantennas for optical sensing.  

Close cooperation exists with the research groups Schreiber, Broch, Scheele and Chassé (SERS, hybrid structures), Meixner/Zhang and Brecht (plasmonics, optical antennas), Meyer (EELS) and Rupp (nanostructured substrates).
