Abstract
A field emission electron source (10) includes a conductive base (12), a carbon nanotube (14), and a film of metal (16). The conductive base includes a top (122). One end (142) of the carbon nanotube is electrically connected with the top of the conductive base. The other end (144) of the carbon nanotube extends outwardly away from the top of the conductive base. The film of metal is formed on the nearly entire surface of the carbon nanotube and at least on the portion of the top of the conductive base proximate the carbon nanotube. A method for manufacturing the described field emission electron source is also provided.
