摘要： An analysis device includes an electron emission element, a collector, an electric field former, a power source, and a controller. The electron emission element includes a bottom electrode, a surface electrode, and an intermediate layer arranged between the bottom electrode and the surface electrode. The power source and the controller allow application of a voltage between the bottom electrode and the surface electrode. The electric field former forms an electric field in an ion movement region where anions directly or indirectly generated by electrons emitted from the electron emission element move toward the collector. The collector and the controller allow measurement of a current waveform of an electric current made to flow by arrival of anions at the collector. The controller regulates, based on the current waveform, a voltage applied between the bottom electrode and the surface electrode.

摘要： An electron emitting device includes a lower electrode, a surface electrode, an electron acceleration layer between the lower electrode and the surface electrode, and an electrode selecting unit. The electron acceleration layer is made of at least an insulating material. At least one of the lower electrode and the surface electrode is a stripe-pattern electrode including a plurality of unit electrodes that are regularly arranged. The electrode selecting unit sequentially selects, from among the plurality of unit electrodes, a unit electrode to which a voltage is to be applied. A voltage is applied between the lower electrode and the surface electrode to accelerate electrons between the lower electrode and the surface electrode, so that the electrons are emitted from the surface electrode.

摘要： This electron emitting element includes a lower electrode, a surface electrode facing the lower electrode, a resistance layer arranged between the lower electrode and the surface electrode, and an insulating layer arranged between the lower electrode and the surface electrode. The resistance layer is an insulating resin layer containing conductive fine particles in a dispersed state. The insulating layer has a peripheral region for defining the electron emission region, and an emission control region which is arranged so as to overlap the electron emission region defined by the peripheral region. The emission control region is configured by a line-shaped insulating layer, a plurality of dot-shaped insulating layers, or both a line-shaped insulating layer and a plurality of dot-shaped insulating layers. The percentage of an area that the emission control region represents within an area of an electron emission region defined by the peripheral region is 2% or more and 60% or less.
