摘要： The invention discloses a photocathode comprising an amorphous substrate such as a glass substrate (110) presenting an input face that will receive incident photons and a back face opposite the front face. Nanowires (120) made from at least one III-V semiconducting material are deposited on the back face of the substrate and extend from this face in a direction away from the front face. The invention also relates to a method for manufacturing such a photocathode by MBE.

摘要： A method of manufacturing a multi-layer image intensifier wafer includes fabricating first and second glass wafers, each having an array of cavities that extend between respective openings in first and second surfaces of the respective glass wafer; doping a semiconductor wafer to generate a plurality of electrons for each electron that impinges a first surface of the semiconductor wafer and to direct the plurality of electrons to a second surface of the semiconductor wafer, bonding a photo-cathode wafer to the first glass wafer; bonding the semiconductor wafer between the first and second glass wafers, and bonding the second glass wafer between the semiconductor wafer and an anode wafer (e.g., a phosphor screen or other electron detector). A section of the multi-layer image intensifier wafer may be sliced and evacuated to provide a multi-layer image intensifier.

摘要： An electron multiplier production method including a main body portion, and a channel provided in the main body portion to open at one end surface and the other end surface of the main body portion and emits secondary electrons includes a first step of preparing a main body member including the one end surface and the other end surface, a communicating hole for the channel through which the one end surface and the other end surface communicate being provided in the main body member, a second step of forming the channel by forming a deposition layer including at least a resistive layer on an outer surface of the main body member and an inner surface of the communicating hole using an atomic layer deposition method, and a third step of forming the main body portion by removing the deposition layer formed on the outer surface of the main body member.

摘要： A dual-spectrum photocathode capable of emitting photo-electrons into a first vacuum space includes a first photodetector array formed using a first optoelectronic material that generates photo-electrons responsive to incident electromagnetic energy in a first spectral band. The dual-spectrum photocathode also includes a second photodetector array formed using a second optoelectronic material that generates photo-electrons responsive to incident electromagnetic energy in a second spectral band that is different from the first spectral band. The first spectral band may include the visible electromagnetic spectrum between 390 nanometers and 700 nanometers and the second spectral band may include the short-wave infrared (SWIR) electromagnetic spectrum above 900 nanometers.

摘要： A process of fabricating a discrete-dynode electron multiplier (DDEM) including the steps of mounting an insulator block to a conductor block, and forming a series of ion-optics geometrical structures in the conductor block, each ion-optics geometrical structure having a smallest dimension of less than 1 millimeter. The forming step may be performed by electrical discharge machining (EDM), laser cutting, and/or water jet cutting.

摘要： Technologies are described for methods for fabricating a film component. The methods may comprise sputtering a first film onto a substrate. The first film may include a semiconductor compound material. The semiconductor compound material may include a semi-metal material and one or more alkali material. The methods may further comprise evaporating a second film onto the first film. The second film may include the one or more alkali materials. The one or more alkali materials may catalyze crystallization of the semiconductor compound material in the first film substantially throughout the first film to form the film component in the first layer.

摘要： A method for providing a superconducting surface on a laser-driven niobium cathode in order to increase the effective quantum efficiency. The enhanced surface increases the effective quantum efficiency by improving the laser absorption of the surface and enhancing the local electric field. The surface preparation method makes feasible the construction of superconducting radio frequency injectors with niobium as the photocathode. An array of nano-structures are provided on a flat surface of niobium. The nano-structures are dimensionally tailored to interact with a laser of specific wavelength to thereby increase the electron yield of the surface.

摘要： Embodiments of a method for forming a field emission diode for an electrostatic discharge device include forming a first electrode, a sacrificial layer, and a second electrode. The sacrificial layer separates the first and second electrodes. The method further includes forming a cavity between the first and second electrode by removing the sacrificial layer. The cavity separates the first and second electrodes. The method further includes depositing an electron emission material on at least one of the first and second electrodes through at least one access hole after formation of the first and second electrodes. The access hole is located remotely from a location of electron emission on the first and second electrode.
