Aerosol Jet-Printed Organic Thin Film Transistors - Performance Analysis and Optimization — •Arno John, Hanna Krikcziokat, and Klaus Meerholz — Institut für Physikalische Chemie, Universität Köln

For the success of organic thin film transistors (OTFTs) in industrial applications it is essential to process devices by printing in order to radically lower production costs. Aerosol jet is a direct-write printing method which provides the user great control over material deposition. Along with layout flexibility and material compatibility, this makes this printing technology an excellent tool for fast prototyping devices.

We use aerosol jet technology to fabricate entire p- and n-type OTFTs by printing Ag-ink (source/drain electrodes), PTAA (p-type semiconductor) and N2200 (n-type semiconductor), PMMA (dielectric) and PEDOT:PSS (gate electrode). By varying parameters for individual components and evaluating the resulting transistors we optimize the printing process.

The performance of printed components is compared to evaporated and spin coated transistor components. We show that, with optimized processing parameters, it is possible to print transistors with charge carrier mobility, output current on/off ratio and threshold voltage of nearly equal quality of non-printed transistors.
