Integrable single walled carbon nanotube (SWNT) network based thin film transistors using roll-to-roll gravure and inkjet

Single walled carbon nanotube network (SWNTn) based thin film transistors (TFTs) were printed using roll-to-roll (R2R) gravure and inkjet on plastic foils to show the integrablility in point of mass production with a low cost. Based on the extracted parameters from printed drive and load TFTs with SWNTn (SWNTn–TFTs), the inverter and ring oscillator were simulated and compared with experimentally measured results of the printed circuits so that the limiting factors to integrate printed SWNTn–TFTs on the plastic foils has been addressed.

► Novel gravure and inkjet hybrid printing technique was developed to print flexible transistors.
► Fully printed circuits were simulated and compared with experimental results.
► Mismatch between simulated and experimental values originated from registration accuracy.
► The integrated circuits can be applicable to flexible electronics with <20 V in mass production.
