摘要
The present invention relates to field emission deices fabrication using carbon nanotube film as a cathode. The multi-wall carbon nanotubes film possesses low electron field emission and high emission current density, which is deposited by catalytic chemical vapor deposition at low temperature. The carbon nanotubes density can be controlled by tuning of the transition metal catalysts in the seed alloy layer. The film can be deposited onto the substrate uniformly with large area. The present invention is related to the fabrication of cold electron sources, florescent light, vacuum electronic devices, field emission displays and methods of making same.
