Abstract
A field emission device (10) has a gate (17) including an opening (22) for the communication of electrons from an emitter (14) to an anode (16). A resistive layer (18) is disposed at least on the inner surface (23) of the gate (17) surrounding the opening (22). The field emission device (10) may further include an insulating, dielectric layer (19). The resistive layer (18) and the dielectric layer (19) reduce arcing between the emitter (14) and the gate (17) in the field emission device (10).
