Abstract

This paper describes a high-speed thin-film transistor (TFT) printed on a regular transparency film. The carrier transport layer of this TFT is a high-density ultrapure carbon nanotube (CNT) thin film formed at room temperature by dispensing a tiny droplet of an electronic-grade CNT aqueous solution that does not contain any surfactant. This CNT-TFT exhibited a high modulation speed of 312 MHz. The unique printing compatible process demonstrated herein would enable mass production of large-area electronic circuits on virtually any desired flexible substrate at low cost and high throughput.
