Bulk Amounts of (6,5) Carbon Nanotubes for (Opto)- Electronic Devices — •Jana Zaumseil — Ruprecht-Karls-Universität Heidelberg, Heidelberg, Germany

Large volumes of highly purified dispersions of semiconducting (6,5) single-walled carbon nanotubes are readily available through polymerwrapping and shear-force mixing. They enable the deposition (e.g. by aerosol jet printing) of semiconducting nanotube layers of variable thickness from sparse networks to 300 nm thick films with large optical density. These layers can be applied in lateral and vertical field-effect transistors with excellent device performance, but also as electrochromic filters, for organic light-emitting diodes in the near-infrared and photovoltaic cells. Here, we present examples of such applications and investigate the impact of novel n-dopants on nanotube networks, temperature-dependent charge transport and their optical properties at different charge carrier densities.
