High Current, Low Voltage Carbon Nanotube Enabled Vertical Organic Field Effect Transistors

Abstract
State-of-the-art performance is demonstrated from a carbon nanotube enabled vertical field effect transistor using an organic channel material. The device exhibits an on/off current ratio >105 for a gate voltage range of 4 V with a current density output exceeding 50 mA/cm2. The architecture enables submicrometer channel lengths while avoiding high-resolution patterning. The ability to drive high currents and inexpensive fabrication may provide the solution for the so-called OLED backplane problem.
