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

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 16×16 pixels driving circuit for an active matrix organic light emitting diode display. The single pixel unit demonstrated a hole mobility of 65 cm²/V^-1s^-1, an on/off ratio of 10⁴ and an on-current of 8 μA.
