Carbon nanotube thin-film transistors and driving circuits for flexible display application

Abstract

Single-walled carbon nanotube is promising for fabricating flexible thin-film transistors due to its excellent carrier mobility, mechanical flexibility, heat tolerance and low-temperature processing. Here, we report a design, fabrication and performance evaluation of a carbon nanotube thin-film transistor with a photoresist layer as the dielectric, and a 16x16 pixels driving circuit for an active matrix organic light emitting diode display. The single pixel unit demonstrated a hole mobility of 65 cm2/V-1<.sup>s-1, an on/off ratio of 104 and an on-current of 8 μA.
