Abstract:
A method for fabricating an electron field emission cathode, the field emission cathode including a substrate having a field emission material layer engaged therewith, where the field emission material incorporates a carbon nanotube material and a metal oxide. The field emission material is produced via a sol-gel process to improve field emission characteristics of the field emission cathode and field emission cathode devices implementing such cathodes.
