Zusammenfassung:Low‐voltage p‐channel and n‐channel organic transistors with channel lengths down to 0.5 μm using four small‐molecule semiconductors and ultra‐thin dielectrics based on two different phosphonic acid monolayers are fabricated on plastic substrates and studied in terms of effective mobility, intrinsic mobility and contact resistance. For the optimum materials combination, flexible complementary circuits have signal delays of 3.1 μs at 5 V
