Abstract

Using a novel high-speed, femtoliter-scale, micro-gravure printing with unprecedented scaling to the sub-10 μm regime and appropriately formulated, characterized, and optimized nanoparticle and polymer ink materials, highly scaled organic thin-film-transistors (OTFTs) are realized. They have excellent DC and AC characteristics and achieve record transition frequencies of 300 kHz, which opens up new classes of applications.
