Abstract: High-current density field emission sources using arrays of nanofeatures bundles and methods of manufacturing such field emission sources are provided. Variable field emission performance is provided with the variance in the bundle diameter and the inter-bundle spacing, and optimal geometries for the lithographically patterned arrays were determined. Arrays of 1-μm and 2-μm diameter multi-walled carbon nanotube bundles spaced 5 μm apart (edge-to-edge spacing) were identified as the most optimum combination, routinely producing 1.5 to 1.8 A/cm2 at low electric fields of approximately 4 V/μm, rising to >6 A/cm2 at 20 V/μm over a ˜100-μm-diameter area.

Abstract: The present invention provides carbon nanotubes perpendicularly and densely deposited over a wide area of a substrate. The carbon nanotubes are manufactured by supplying alternating-current power at a specific frequency between an anode and a cathode disposed in a reactor, and causing plasma to be generated between the anode and the cathode by introducing mixed gas containing an aliphatic hydrocarbon having 1-5 carbon atoms and hydrogen or mixed gas containing an aromatic hydrocarbon and hydrogen. The substrate is disposed between the anode and the cathode and held at a distance two times or less of the mean free path of a hydrocarbon cation from the anode.

Abstract: A carbon nanotube suspension uses water as the basic solvent added with dispersant, stabilizer, coalescing aid, adhesion promoter, and a carbon nanotube. The basic solvent and the above solutes form a low viscosity solvent with carbon nanotube suspending therein. Therefore, the carbon nanotube suspension is formed to serve as a source material of the electron emission source of a field-emission display. That is, the carbon nanotube can be coated on a surface for forming the carbon nanotube electron-emission layer.
