Abstract :
Printed electronics is expected to be a low-cost, eco-friendly, and on-demand fabrication technology because it decreases the number of process steps and the amount of waste materials. Carbon nanotube (CNT) transistor arrays were fabricated on plastic films by maskless printing without any additional pattering process, and minimum materials were used. During fabrication, the morphology of the CNT random network was controlled by an adsorption mechanism on the surface to be printed, which resulted in excellent and uniform electrical properties. Based on the fabrication technology, various types of CNT ink were examined. A guiding principle for developing CNT ink was shown to improve the TFT performance.
