    Abstract

    We present a novel ion enhanced organic transistor using a thick, ion conducting mem-brane (MemFET). The membrane acts both as gate insulator and as mechanical sup-port. The fabrication of the membranes starts with a PVDF-film as base material, which is functionalized by the roll-to-roll suitable electron beam irradiation induced grafting technique. For comparison, we have also used the commercially available Nafionr-membrane. The MemFETs are fabricated by standard laboratory fabrication techniques using soluble conducting and semiconducting polymers. The MemFETs operate at 1 V.
