Solution processing of vertical organic field-effect transistors with TIPS-Pentacene — •David Kneppe, Alrun Günther, Michael Sawatzki, and Karl Leo — Dresden Integrated Center for Applied Physics and Photonic Materials, Dresden, Germany

The interest in organic transistors has been growing rapidly in the past years due to their importance for the realization of future organic electronic devices such as flexible displays or logic applications. By using a novel device architecture with a short channel length and a high mobility organic semiconductor, key parameters like the maximum drain current as well as the switching frequency can be improved further. Therefore, vertical organic field-effect transistors (VOFETs) with vertical channel lengths in a regime of several nanometers are promising devices. Here, organic semiconductors with a high charge carrier mobility especially in the vertical direction are needed. However, vacuum deposition of several layers to produce these devices is rather expensive for later massive industrial fabrication. Here, first approaches in solution processing of VOFETs with the promising polycrystalline organic semiconductor TIPS-Pentacene are presented.
