Abstract
A method for manufacturing a carbon nanotube field emission cathode includes the steps of: providing a substrate () with a metallic layer () thereon; defining holes () in the metallic layer; oxidizing the metallic layer to form a metallic oxide layer () thereon; removing portions of the metallic oxide layer in the holes so as to expose corresponding portions of the metallic layer; forming a metal-salt catalyst layer () on the exposed portions of the metallic layer in the holes; and growing carbon nanotubes () on the substrate in the holes.
