Abstract:
A method for manufacturing a field emission electrode by using an array of a nano-wire is provided to enhance largely a high field emission effect by using characteristics of the nano-wire. Dispersion is formed by diluting a nano-wire or a nano-wire including magnetic particles in an organic solvent. The dispersion is dispersed into a base fixed to a top end of a magnetic field generation unit. The organic solvent is evaporated from the dispersion of the base so that the nano-wire is aligned at an arbitrary angle in a vertical line or a horizontal line or between the vertical line and the horizontal line along a magnetic field direction in the magnetic field. A metal is deposited on the base in order to fix the aligned nano-wire on the base.
Abstract:
An electron emitter is formed by in situ growth from the vapor on catalyst clusters that are adhered by an adhesion layer to a conductive electrode. The emitter comprises hemispheroidal nanofiber clusters that emit electrons at low field strengths and high current densities, producing bright light by the interaction of the electrons and a fluorescent and/or phosphorescent film on an anode spaced across an evacuated gap. The nanofibers may be grown such that the nanofiber clusters are entangled, restricting movement of individual nanofibers.
