Ink-Jet Printing of Carbon Nanotube Thin-Film Transistors on Flexible Plastic Substrates

Ink-jet printable thin-film transistors (TFTs) on flexible plastic substrates are an important focus of research because present silicon-based electronics cannot realize such devices. In the present study, we fabricated single-walled carbon nanotube (SWCNT) TFTs on plastic substrates using the ink-jet printing method, and realized high-on/off current ratio (?104) and flexibility, respectively. The present study therefore represents a major step towards "flexible SWCNT electronics".
