Abstract (en)
[origin: WO9428571A1] A field emission cathode includes a layer of conductive material (14) and a layer of amorphic diamond film (12), functioning as a low effective work-function material, deposited over the conductive material to form emission sites. The emission sites each contain at least two sub-regions having differing electron affinities.
