Abstract
The present disclosure may provide a field emission device with an enhanced beam convergence. For this, the device may include a gate structure disposed between a cathode electrode and an anode electrode, wherein the gate structure includes a gate electrode and an atomic layer sheet disposed on the gate electrode, the gate electrode facing an emitter and having at least one aperture formed therein.
Claims9
A field emission device comprising:
- a cathode electrode;
- at least one emitter on the cathode electrode;
- an anode electrode disposed away in a longitudinal direction of the device from the cathode electrode;
- and
- a gate structure disposed between the cathode electrode and the anode electrode, wherein the gate structure includes a gate electrode and an atomic layer sheet disposed on the gate electrode, the gate electrode facing the emitter and having at least one aperture formed therein.
