- Abstract
- Provided is a field emission device. The field emission device includes a cathode electrode having a first surface and a second surface facing the first surface, the cathode electrode including grooves that are recessed from the first surface toward the second surface, the grooves extending in a first direction parallel to the first surface and emitter structures which are disposed within the grooves and each of which includes a core extending in the first direction and a conductive wire configured to surround the core. The grooves may be arranged in a second direction crossing the first direction, and the emitter structures may be disposed at vertical levels different from each other.
