Electron emitting element, devices utilizing said element, and method for producing said element

摘要

The present invention provides an electron emitting element, comprising: a first electrode; an insulating fine particle layer formed on the first electrode and composed of insulating fine particles; and a second electrode formed on the insulating fine particle layer, wherein the insulating fine particle layer is provided with recesses formed in a surface thereof, the surface facing the second electrode, the recesses each having a depth smaller than a thickness of the insulating fine particle layer, and when a voltage is applied between the first electrode and the second electrode, electrons provided from the first electrode are accelerated in the insulating fine particle layer to be emitted though the second electrode.

1. An electron emitting element, comprising:
a first electrode; an insulating fine particle layer formed on the first electrode and composed of insulating fine particles; and a second electrode formed on the insulating fine particle layer, wherein the insulating fine particle layer is provided with recesses formed in a surface thereof, the surface facing the second electrode, the recesses each having a depth smaller than a thickness of the insulating fine particle layer, when a voltage is applied between the first electrode and the second electrode, electrons provided from the first electrode are accelerated in the insulating fine particle layer to be emitted though the second electrode, and wherein the recesses are obtained by forming a layer containing the insulating fine particles and organic fine particles on the first electrode so that the layer has a thickness larger than a maximum diameter of the organic fine particles, and then decomposing the organic fine particles.
