FIELD ELECTRON EMITTER, FIELD ELECTRON EMITTER DEVICE AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: An electric-field electron emitter, an electric-field electron emitting element including the emitter, and a method for manufacturing the same are provided to reduce a manufacturing cost by integrating a metal electrode and an electric-field emitting tip. CONSTITUTION: A carbon nano-tube(121) is integrated to metal electrodes(120, 140) and is protruded on the surface of the electrodes. The electrode additionally contains nucleic acid. The nano-tube of electrodes is plated with the nucleic acid. The electrodes contains one or more metal from a group including Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Ag, Au, Hg, Pt, Ta, Mo, Zr, Ta, Mg, Sn, Ge, Y, Nb, Tc, Ru, Rh, Lu, Hf, W, Re, Os, Ir, Lr, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg and Uub.
