Flat panel display prototype using gated carbon nanotube field emitters

A flat panel display prototype has been fabricated using gated carbon nanotubes as electron emission source. The gate structure is made by a self-aligned method. The pixels are turned on and off by controlling the gate electrode with a 50 V source. The operating properties of the display show much promise for further development. It is believed that this technology can lead to easy-to-make and inexpensive flat panel displays with low driving voltage. (C) 2001 American Institute of Physics.
