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.

Abstract: A method and system for cleaning a field emission cathode device, the field emission cathode device including a substrate having a field emission layer engaged therewith, includes engaging the field emission cathode device with a vibration device such that the substrate is disposed above the field emission layer. The field emission cathode device is then vibrated with the vibration device in an X, Y, or Z direction at a predetermined frequency and at a predetermined amplitude for a predetermined time duration so as to clean the field emission cathode device by dislodging non-embedded particles from the field emission layer.
