    Abstract: A comb-shaped electrode is formed on the main surface of a ferroelectric thin film and a planar electrode is formed on the rear surface of a ferroelectric thin film. Then, the property of the main surface of the ferroelectric thin film is converted into semi-conduction. Then, the assembly comprised of the ferroelectric thin film, the comb-shaped electrode and the planar electrode is disposed in a given atmosphere. Under this condition, a negative voltage is applied to the comb-shaped electrode to polarize the ferroelectric thin film, and a negative impulse voltage is applied to the planar electrode, thereby generating electron beams from the main surface of the ferroelectric thin film.

    Abstract: A high emission electron emitter and a method of fabricating a high emission electron emitter are disclosed. A high emission electron emitter includes an electron injection layer, an active layer of high porosity porous silicon material in contact with the electron injection layer, a contact layer of low porosity porous silicon material in contact with the active layer and including an interface surface with a heavily doped region, and an optional top electrode in contact with the contact layer. The contact layer reduces contact resistance between the active layer and the top electrode and the heavily doped region reduces resistivity of the contact layer thereby increasing electron emission efficiency and stable electron emission from the top electrode. The electron injection layer is made from an electrically conductive material such as n+ semiconductor, n+ single crystal silicon, a metal, a silicide, or a nitride. The active layer and the contact layer are formed in a layer of silicon material that is deposited on the electron injection layer and then electrochemically anodized in a hydrofluoric acid solution. Prior to the anodization, the interface surface can be doped to form the heavily doped region. The layer of silicon material can be porous epitaxial silicon, porous polysilicon, porous amorphous silicon, and porous silicon carbide.

    Abstract: The field emission planar electron emitter device is disclosed that has an emitter electrode, an extractor electrode, and a planar emitter emission layer, electrically coupled to the emitter electrode and the extractor electrode. The planar electron emitter is configured to bias electron emission in a central region of the emission layer in preference to an outer region thereof. One structural example that provides this biasing is achieved by fabricating the planar emitter emission layer so that it has an outer perimeter that is thicker in depth than at an interior portion of the planar emitter emission layer, which reduces electron beam emission at the outer perimeter when an electric field is applied between the emitter electrode and the extractor electrode. The electric field draws emission electrons from the surface of the planar emitter emission layer towards the extractor electrode at a higher rate at the interior portion than at the outer perimeter. The planar electron emitter device further includes a focusing electrode electrically coupled to the planar electron emitter.
