Abstract

Low-cost green manufacturing of single-walled carbon nanotube films via precisely controlled inkjet printing is demonstrated. This type of transistor exceeds the performance of conventional organic transistors, both in mobility and the on/off ratio. The production of exclusively inkjet-printed SWCNT transistors with printable ionic-liquid gate dielectrics is also shown.
