APPARATUS FOR REMOVAL OF SURFACE OXIDES VIA FLUXLESS TECHNIQUE INVOLVING ELECTRON ATTACHMENT CAPABLE OF REDUCING ONSET VOLTAGE FOR ELECTRON EMISSION BY USING THE SURFACE OF AN ANODE AND A METHOD THEREOF

摘要

PURPOSE: An apparatus for removal of surface oxides via fluxless technique involving electron attachment and a method thereof are provided to make the polarization of the PZT(Lead Zirconate Titanate) between a cathode and an anode play a role in intensifying an electric field and accumulating electrons on the cathode, thereby facilitating field emission of electrons.;CONSTITUTION: An apparatus for removal of surface oxides via fluxless technique involving electron attachment comprises a cathode(20), a dielectric material, and an anode. The cathode has an angled edge and includes a conductive material which has a work function ranging from 2 to 5eV. The dielectric material surrounds at least a portion of the cathode. The anode includes a conductive material which surrounds at least a portion of the dielectric material. The cathode and the anode are each connected to an electrical voltage source. The dielectric material between the cathode and the anode is polarized to provide an intensified electric field and to accumulate electrons at the edge of the cathode and thus generate electrons from the cathode. A gas mixture further includes a carrier gas selected from the group consisting of nitrogen, helium, neon, argon, krypton, xenon, radon, and mixtures thereof.;COPYRIGHT KIPO 2013
