The Zaumseil group is mainly interested in carbon-based materials (single-walled carbon nanotubes and organic semiconductors) for a wide range of optoelectronic devices. The focus is on charge transport in thin film transistors but also on strong light-matter interaction for light emission and detection in the near-infrared. Their activities encompass the entire process chain from the purification of monochiral semiconducting carbon nanotubes, spectroscopic investigation, film and device processing (e.g., by aerosol-jet printing), and characterization for state-of-the-art solution-processed materials. Recent highlights include the demonstration of electrically pumped near-infrared exciton-polaritons in cavity-integrated carbon nanotube, as well as donor-acceptor polymer light-emitting transistors and n-doping of carbon nanotube network transistors.
