Abstract

High performance organic thin-film transistors and inverters operating at MHz frequencies at 10 V are fabricated on plastic with high throughput (printing speed up to 1.0 m/s) using attoliter-scale high-speed gravure printing. The high performance of the devices is achieved using highly scaled gravure printed features (smaller than 5 μm) and optimizing a high mobility organic semiconductor for the short-channel gravure printed devices (>0.5 cm2/V s) to realize record performance levels.
