A high-performance all-inkjetted organic transistor technology

We report on the highest performance all-printed transistors reported to date. Using nanoparticle-based printed contact, polymer dielectrics, and a printed soluble pentacene precursor semiconductor, we demonstrate all-inkjetted devices with mobilities >0.1cm/sup 2//V-s and on-off ratios as high as 10/sup 4/. The performance of these devices is comparable to control devices fabricated on silicon-substrates, and thus, these devices represent a significant step towards the realization of low-cost printed electronics.
