Welcome to the homepage of the Hybrid Nanosystems Research Group at the University of Munich and Imperial College London. We conduct internationally leading research in nanophotonics, plasmonics, and energy conversion. Find out more about us on these pages.
At the end of 2018 we will move into our new building, the Nanoinstitute Munich at the beautiful Englischer Garten in Munich.
- we are looking to establish two subgroups, in Ultrafast physics of interfaces, and Novel hybrid optoelectronic materials. Candidates interested in leading these subgroups please contact me.
- postdoc and junior group leader (habilitation) positions available in nanoscale energy conversion, ultrafast optics, and nanophotonics, starting January 2019. Please e-mail me directly!
- newest publication: hot-electron-mediated super-resolution imaging of absorption in metallic nanocavities

We work on the fundamentals of light/matter interactions in nanostructured materials, from the visible to the mid-infrared part of the spectrum. A particular focus lies on plasmonic and dielectric nanoantennas, which we utilise for solar-to-chemical energy conversion, coupling to low-dimensional materials, and the study of quantum phenomena.
Designer metallic nanostructures, called plasmonic nanoantennas, enable us to confine optical fields deep below the diffraction limit, over distances of only a few cubic nanometers. Molecules or quantum matter experiencing these enhanced fields show a vast increase in their interactions which photons. We exploit this for surface-enhanced optical spectroscopies.
When surface plasmons decay, hot electron/hole pairs are generated, and within a lifetime of a few dozen femtoseconds these energetic carriers can trigger chemical reactions in nanoscale regions on their surface. We research the fundamentals of such plasmon-enabled chemistry, with the goal of increasing the efficiency of solar-to-chemical energy conversion via photocatalysis.
Semiconducting nanoantennas consisting of silicon, germanium, or gallium phosphide enable us to enhance nonlinear optical processes by many orders of magnitude. Electric, magnetic and toroidal electromagnetic modes confine electromagnetic fields in a controlled manner. These properties are also very valuable for surface-enhanced spectroscopies without high optical losses.
