Abstract

Flexible, transparent thin-film transistor with active layers composed of carbon nanotube-based conducting ink were fabricated on a plastic substrate by ink-jet printing. The properties of the formulated conducting ink containing carbon nanotubes, a conducting polymer, and additives were characterized and optimized. The conducting ink was applied to flexible thin-film transistors using ink-jet printing.
