Abstract: Disclosed are methods and devices suitable for generating electron beams and pulses of radiation. Specifically, in some disclosed embodiments, multiple emitting electrodes of a ferroelectric emitter are sequentially activated, generating a relatively long electron beam pulse that is substantially a series of substantially consecutive short electron beam pulses generated by the sequentially-activated individual emitting electrodes.

Abstract: Provided is a piezoelectric-film-type electron emitter of high durability exhibiting suppressed reduction in electron emission quantity, which reduction would otherwise occur with repeated use of the electron emitter. The electron emitter includes a substrate, a lower electrode, an emitter layer, and an upper electrode. The upper electrode has a plurality of openings, and an emitter section located on the top surface of the emitter layer is exposed through the openings to a reduced-pressure atmosphere. The electron emitter is configured so that when a pulse drive voltage Va is applied between the lower electrode and the upper electrode, electrons are accumulated on the emitter section, and then the electrons are emitted toward the reduced-pressure atmosphere. The emitter layer contains a primary component (i.e., a ferroelectric composition) and an additional component. The additional component contains a transition metal oxide of high oxidation number which can serve as an oxidizing agent by being converted into an oxide of the transition metal of lower oxidation number.

Abstract: A thin film of ferroelectric layered superlattice material in a flat panel display device is energized to selectively influence the display image. In one embodiment, a voltage pulse causes the layered superlattice material to emit electrons that impinge upon a phosphor, causing the phosphor to emit light. In another embodiment, an electric potential creates a remanent polarization in the layered superlattice material, which exerts an electric field in liquid crystal layer, thereby influencing the transmissivity of light through the liquid crystal. The layered superlattice material is a metal oxide formed using an inventive liquid precursor containing an alkoxycarboxylate. The thin film thickness is preferably in the range 50-140 nm, so that polarizabilty and transparency of the thin film is enhanced. A display element may comprise a varistor device to prevent cross-talk between pixels and to enable sudden polarization switching. A functional gradient in the ferroelectric thin film enhances electron emission. Two ferroelectric elements, one on either side of the phosphor may be used to enhance luminescence. A phosphor can be sandwiched between a dielectric and a ferroelectric to enhance emission.

Abstract: A method of operating cold cathode in discharge lamps, including discharge lamps operating with a dielectrically hindered discharge that include two electroconducive electrodes facing each other between which a ferro-electric material is sandwiched. At least one of the electrodes presents one or more openings. When the cathode is operating, a voltage of quickly alternating polarity is applied to both electrodes, thereby freeing electrons on the surface of the ferro-electric material. The working voltage of the discharge lamp causes an acceleration of said electrons, which pass through the openings towards the anode and are used for igniting the discharge lamp and keeping it in an operating mode.

Abstract: A ferroelectric cold cathode comprising a ferroelectric layer formed of a ferroelectric material and provided on its one surface with an emitter which is a projection having a sharp tip portion, a first electrode layer formed on one surface of the ferroelectric layer and having an opening allowing the sharp tip portion of the emitter to be exposed therethrough, and a second electrode layer formed on the other surface of the ferroelectric layer. When a voltage is applied between the first electrode and the second electrode, a dielectric polarization is reversed in the ferroelectric layer, resulting in the emission of electrons from the sharp tip portion of the emitter.

Abstract: A flat panel display includes a ferroelectric thin film between first and second spaced apart electrodes. The ferroelectric thin film emits electrons upon application of a predetermined voltage between the first and second spaced apart electrodes. The electrons are emitted in an electron emission path and impinge upon a luminescent layer such as a phosphor layer, which produces luminescence upon impingement upon the emitter electrodes. The ferroelectric thin film is preferably about 2 .mu.m or less in thickness and is preferably a polycrystalline ferroelectric thin film. More preferably, the thin ferroelectric film is a highly oriented, polycrystalline thin ferroelectric film. Most preferably, highly oriented ferroelectric thin film has a preferred (001) crystal orientation and is about 2 .mu.m or less in thickness. A flat panel display may be formed of arrays of such display elements. Top and bottom electrodes or side electrodes may be used. The display may be formed using conventional microelectronic fabrication steps.
