摘要： Heat-treating niobium pentoxide powder causes the powder to become agglutinated and bonded while phase transformation from an orthorhombic crystal to a monoclinic crystal occurs and resultantly bar-shaped c-axis-oriented niobium pentoxide particles, the longitudinal direction of which is identical to the c axis direction, are formed. A slurry is produced by mixing the c-axis-oriented niobium pentioxide particles with lithium carbonate and a binder and is molded as a tape by a doctor blade method to form a sheet-shaped compact. By so doing, bar-shaped or columnar c-axis oriented niobium pentoxide particles are aligned in the direction of forming the tape and in the meantime a compact filled with lithium carbonate is produced. By heating the compact, a dielectric layer including a c-axis-oriented lithium niobate polycrystalline material is produced.

摘要： An electron-emitting apparatus includes an emitter section made of a dielectric material, lower electrodes, upper electrodes having micro through holes, insulating layers disposed on the upper surface of the emitter section and between the adjacent upper electrodes, and focusing electrodes to which a predetermine potential is applied and which are disposed on the insulating layers. The electron-emitting apparatus applies a negative potential to the upper electrode to accumulate electrons in the emitter section and then applies a positive potential to the upper electrode. As a result, the polarization of the emitter section is reversed, and the accumulated electrons are emitted through the micro through holes in the upper electrodes by Coulomb repulsion. Owing to electric fields generated by the focusing electrodes, the emitted electrons travel in the upward direction of the upper electrode without spreading into a shape of a cone.
