Abstract : Bilayer ambipolar OFETs based on thermal evaporated and dual‐solution‐shearing (DSS) processed ultra‐thin films as the bottom template layer are described by Paddy Kwok Leung Chan and co‐workers in article number1700268 . The DSS‐processed ultra‐thin films with densely packed long alkyl chains act as a p‐channel active layer and growth template for the upper n‐type semiconductor layer.
