ABSTRACT:
A field emission cathode includes a conductive substrate and a carbon nanotube film disposed on a surface of the conductive substrate. The carbon nanotube film includes a plurality of successive and oriented carbon nanotube bundles parallel to the conductive substrate, the carbon nanotubes partially extrude from the carbon nanotube film. A method for fabricating the field emission cathode includes the steps of: (a) providing a conductive substrate; (b) providing at least one carbon nanotube film, the carbon nanotube film including a plurality of successive and oriented carbon nanotube bundles joined end to end, the carbon nanotube bundles parallel to the conductive substrate, and (c) disposing the at least one carbon nanotube film to the conductive substrate to achieve the field emission cathode.
