Field emission device (FED)

摘要

A Field Emission Device (FED) includes an emitter formed on a cathode electrode and including Carbon NanoTubes (CNTs), and a gate electrode to extract electrons from the emitter. In addition, a RuOx layer or a PdOx layer is coated on the emitter to protect the CNTs and to stabilize the emission from the CNTs. A stabilizer layer to stabilize an emission structure and to protect emission ends is coated on the surface of a CNT emitter or the surfaces of the CNTs, more specifically, the emission ends of the CNTs, in order to prevent abrasion of the CNTs caused by an excess current or an emission process.
