Abstract: There is provided a method of manufacturing a nano-wire using a crystal structure. In the method of manufacturing a nano-wire, a crystal grain having a plurality of crystal faces is used as a seed, and a crystal growing material having a lattice constant difference within a predetermined range is deposited on the crystal grain, thereby allowing the nano-wire to grow from at least one of the crystal faces. Therefore, it is possible to give the positional selectivity with a simple process using a principle of crystal growth and to generate a nano-structure such as a nano-wire, etc. having good crystallinity. Further, it is possible to generate a different-kind junction structure having various shapes by adjusting a feature of a crystal used as a seed.

Abstract: 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.
