A single-walled carbon nanotube (SWNT)-based 1-b full-adder circuit was realized on flexible plastic substrates through an all gravure printing process by minimizing intertransistor process variation and leakage current between crossing interconnects. The circuit comprised 27 printed SWNT thin-film transistors, with a variation of up to only ± 25% in electrical characteristics among them. Furthermore, the circuit showed a maximum propagation delay of 13.7 ms, with a 50-Hz input signal, and a supply voltage of-20 V. The process could be used for low-cost flexible arithmetic logic units in a variety of applications. © 2012 IEEE. Source

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. © 2011 Elsevier B.V.
