Abstract

High-performance single-walled carbon nanotube (SWCNT) thin-film transistors are fabricated by single-pass inkjet printing of SWCNTs on high-κ solution-processed ZrO₂ gate dielectric. We demonstrate that an ultraviolet ozone treatment of the ZrO₂ substrate is critical in achieving a uniform dispersion of sorted SWCNTs in the semiconducting channel. The resulting devices exhibit excellent performance with mobility and on/off current ratio exceeding 30 cm² V^-1 s^-1 and 10⁵, respectively, at low operating voltages (
