    Abstract: An improved method for manufacturing a matching pair of electrodes comprises the steps of: fabricating a first electrode with a substantially flat surface; depositing islands of an oxidizable material over regions of the surface; depositing a layer of a third material over the surface of the first electrode to form a second electrode; separating the first electrode from the second electrode; oxidizing the islands of oxidizable material, which causes the islands to expand; bringing the upper electrode and the lower electrode into close proximity, whereupon the expanded island of oxidizable material touches the upper surface and creates an insulating gap between the two surfaces, thereby forming a matching pairs of electrodes.

    Abstract: A lateral-emitter field emission device has a thin-film emitter cathode 50 which has thickness of not more than several hundred angstroms and has an edge or tip 110 having a small radius of curvature. To form a novel display cell structure, a cathodoluminescent phosphor anode 60 is positioned below the plane of the thin-film lateral-emitter cathode 50, allowing a large portion of the phosphor anode's top surface to emit light in the desired direction. An anode contact layer contacts the phosphor anode 60 from below to form a buried anode contact 90 which does not interfere with light emission. The anode phosphor is precisely spaced apart from the cathode edge or tip and receives electrons emitted by field emission from the edge or tip of the lateral-emitter cathode, when a small bias voltage is applied. The device may be configured as a diode, triode, or tetrode, etc. having one or more control electrodes 140 and/or 170 positioned to allow control of current from the emitter to the phosphor anode by an electrical signal applied to the control electrode. In a particularly simple embodiment, a single control electrode 140 is positioned in a plane below the emitter edge or tip 110 and automatically aligned to that edge. The display cell structure may be repeated many times in an array, and the display cell structure of the invention lends itself to novel array structures which are also disclosed.

    Abstract: An electron gun and a high tension switch permits the achievement of high-power electron beams which are ON-OFF modulated by DC up to frequencies exceeding kHz. The electron gun has a cathode, at least two accelerating electrodes, a cathode heater, and a possible focussing system. The or each accelerating voltage, generated by any source, which may in the case of space applications also be a tether, is applied between accelerating electrodes and cathode, with the exception of an appropriate accelerating electrode to which there is applied, by of the switch, alternately its accelerating voltage or the same voltage as that of the cathode, obtaining an ON-OFF modulation of the electron beam emitted by the gun.

    Abstract: New, hybrid vacuum electronic devices are proposed, in which the electrons are extracted from the nanotube into vacuum. Each nanotube is either placed on the cathode electrode individually or grown normally to the cathode plane. Arrays of the nanotubes are also considered to multiply the output current. Two- and three-terminal device configurations are discussed. In all the cases considered, the device designs are such that both input and output capacitances are extremely low, while the efficiency of the electron extraction into vacuum is very high, so that the estimated operational frequencies are expected to be in a tera-hertz range. New vacuum triode structure with ballistic electron propagation along the nanotube is also considered.

    Abstract: Vacuum diode-based devices, including Vacuum Diode Heat Pumps and Vacuum Thermionic Generators, are described in which the electrodes are coated with an electride. These materials have low work functions, which means that contact potential difference between cathode and anode may be set against the effects of space charge, resulting in an improved device whereby anode and cathode may be set at a greater distance from each other than has been previously envisaged.

    Abstract: A low voltage vacuum field emission device and method for manufacturing is provided. The devices are fabricated by anodizing a heavily doped silicon wafer substrate (12) in concentrated HF solution, forming extremely sharp silicon tips (18) at the silicon to porous silicon interface. The resulting porous silicon layer is then oxidized, and a metal film (22) is deposited by evaporation on the porous silicon. Silicon substrate (12) is the cathode, and metal film dots (22) are the anodes. The I-V characteristics for the field emission devices follow Fowler-Nordheim curves over three decades of current. The I-V characteristics are also utterly independent of temperature up to 250.degree. C. When the oxidized porous silicon layer (OPSL) is about 5000 .ANG., substantial current is obtained with less than 10 volts. Recent experiments leave no doubt that the charge transport is in the vacuum of the pores. A silicon wafer that contains an OPSL may prove to be a very useful material for the fabrication of low voltage, low noise field emitters for vacuum microelectronics.

    Abstract: A vacuum transistor having an optical gate in which an optical signal is radiated from the optical gate. The transistor has a silicon substrate; an insulating layer deposited on said silicon substrate, the insulating layer having a recess portion formed by an etching method; an optical source for radiating the optical signal and serving as said optical gate; and two electrodes formed on said insulating layer and separated from each other under a vacuum or an atmosphere. One of the electrodes receives the optical signal and is an electron emitting electrode for emitting electrons, and the other electrode is an electron collecting electrode for collecting the electrons emitted from said electron emitting electrode. The electron emitting electrode is formed beneath said optical source under a vacuum or an atmosphere and is connected to ground; and said electron collecting electrode is connected to a power source. The amount of current flowing in said electron collecting electrode may be adjusted by the intensity of the optical signal from said optical source. The mobility of electrons between the electron emitting electrode and the electron collecting electrode is further improved owing to a vacuum state or an atmosphere state of the electron transferring path.
