   Abstract of the SELF-FLEX-APP project:

  Plastic transistors do not only create an interesting field of science but also belong to a highly promising technology for future devices. To reduce production costs, new processing ideas are required. One approach is focused on the deposition of the substrate polymer together with the organic semiconductor from one solution. During solvent evaporation or post-treatment, a vertical phase separation between the isolating polymer and the semiconductor occurs. The semiconductor crystallizes on the film surface creating the active layer for the charge carrier transport. On the other hand, the isolating polymer forms both the film carrier and the necessary dielectric for the transistor which separates the gate electrode from the semiconductor. As the electrode material, a graphene-based ink is developed which is applied to the flexible films by inkjet printing. These electrodes will ensure an unhindered charge carrier injection into the active layer even under pronounced bending conditions.
