摘要： A crystallographically-oriented ceramic including first regions, in which crystal nuclei remain and which contain a specific element in a predetermined concentration range and extend at least partially in a layered shape along a crystal plane, and second regions, which contain the specific element in a different concentration range from the first regions and extend at least partially in a layered shape along the crystal plane. The regions are alternately repeated, and a compositional distribution exists in a direction orthogonal to the crystal plane. In the first region, the concentration of Na is higher, the concentration of K is lower, the concentration of Nb is lower, and the concentration of Ta is higher than the second region, and in the second region, the concentration of Na is lower, the concentration of K is higher, the concentration of Nb is higher, and the concentration of Ta is lower than the first region.

摘要： An electron emitter includes an emitter layer formed of a dielectric material, an upper electrode, and a lower electrode. A drive voltage is applied between the upper electrode and the lower electrode, for emitting electrons. The upper electrode is formed of scale-like conductive particles on the upper surface of the emitter layer and has a plurality of opening portions. The surfaces of overhanging portions of the opening portions that face the emitter layer are apart from the emitter layer. The overhanging portions each have such a cross-sectional shape as to be acutely pointed toward the inner edge of the opening portion, or the tip end of the overhanging portion, so that lines of electric force concentrate at the inner edge.

摘要： An electron emitter includes an emitter layer composed of a dielectric material, a first electrode disposed onto a first surface of the emitter layer, and a second electrode disposed onto the first surface, inside, or onto a second surface opposite to the first surface of the emitter layer. A microscopic recess is disposed on a surface of the first electrode. Alternatively, an opening is disposed in the first electrode, the opening exposing the first surface of the emitter layer to the outside of the electron emitter, and a plurality of microscopic protrusions are disposed along the thickness direction of the first electrode at an inner edge of the opening.
