Abstract: An electrode structure for a field emission vacuum device comprises an array of emitter tips (1) of micron dimensions protruding from a substrate (6) and an overlying grid layer (5) with an aperture (3) therethrough. A thin coating of material is formed over each tip by evaporation or sputtering of the material. An insulating spacer layer (7) between the substrate and the grid layer also has an aperture (9) encircling each emitter tip, the aperture in the insulating layer being of larger diameter than that in the grid layer, so that the evaporated or sputtered material does not reach the wall of the aperture in the insulating layer to cause a grid/cathode short-circuit. The evaporated or sputtered thin film may be formed of, for example, Pd, Ir or Pt.

Abstract: A stable cold field electron emitter is produced by forming a coating on an emitter base material. The coating protects the emitter from the adsorption of residual gases and from the impact of ions, so that the cold field emitter exhibits short term and long term stability at relatively high pressures and reasonable angular electron emission.

Abstract: A field-emission electron source element includes a cathode substrate, an insulating layer that is formed on the cathode substrate and has an opening, a lead electrode formed on the insulating layer, and an emitter formed in the opening. A surface layer of an electron emitting region of the emitter is doped with at least one reducing element selected from the group consisting of hydrogen and carbon monoxide. Further, an image display apparatus including the above-mentioned field-emission electron source element is provided. This makes it possible to obtain not only a stable field-emission electron source element that does not cause a current drop even after a high current density operation for a long time but also a high-performance image display apparatus that can maintain a stable display performance over a long period of time.
