Abstract: An apparatus for high speed gating of electric current based on the resonant interaction of tunneling electrons with optical fields is disclosed. The present invention biases an electron-emitting tip with a DC voltage source and focuses an output from a laser on the electron-emitting tip to stimulate electron emission from the tip. The electron emission creates an electrical signal that is coupled to circuitry for further processing. In accordance with the present invention, various methods of coupling the electrical signal from the electron-emitting tip are disclosed, as are various methods of reducing the magnitude of the laser output needed to stimulate electron emission, and methods of enhancing the static current density.

Abstract: A vacuum flat panel display has a plurality of associated pixels each having a phosphor and nanotubes and a surrounding control frame. When a pixel voltage is negative relative to the frame then a plurality of electrons emitted by the nanotubes are attracted to the frame whereby electrons strike gas atoms in transit to the frame and produce ions and additional electrons; wherein said ions returning to the pixel result in phosphor illumination. The invention is also a process for illuminating a phosphor in a flat panel display comprising: a plurality of associated pixels each having a phosphor and nanotubes; applying a pixel voltage negative relative to a frame; attracting to the frame a plurality of electrons emitted by the nanotubes; whereby electrons strike atoms of a gas in transit to the frame producing ions resulting in phosphor illumination.

Abstract: An improved device, method, and system efficiently couple high-frequency energy from radiation-assisted field emission. A radiation source radiates an emitting surface with an electromagnetic field. The electromagnetic field reduces the potential barrier at the emitting surface, allowing electrons to tunnel from the surface. The tunneling electrons produce a current. The electron tunneling current oscillates in response to the oscillations of the electromagnetic field radiation. Two or more electromagnetic fields of different frequencies radiate the emitting surface, causing photomixing. The electron tunneling current oscillates in response to the difference of the frequencies of the electromagnetic fields.

Abstract: A vacuum microelectronic device (10,40) emits electrons (37) from surfaces of nanotube emitters (17, 18). Extracting electrons from the surface of each nanotube emitter (17) results is a small voltage variation between each emitter utilized in the device (10, 40). Consequently, the vacuum microelectronic device (10,40) has a more controllable turn-on voltage and a consistent current density from each nanotube emitter (17,18).

Abstract: A radiation assisted electron emission device uses semiconductor or semi-insulator material formed with an emission mechanism such as a field emission tip, a thermionic emission device, or a negative electron affinity emitter as a source of electrons. The material is irradiated with a source of radiation, such as electromagnetic radiation, neutron radiation, or charged particle radiation, which excites electron-hole pairs in the material to generate a population of free conducting electrons. The electrons are driven to the emission mechanism by a suitable transport process, such as diffusion or drift. The electron emission device has applicability to a broad range of technologies where an electron beam or current is used.

Abstract: An electron source is made from mixed-metal carbide materials of high refractory nature. Producing field-enhanced thermionic emission, i.e., thermal-field or extended Schottky emission, from these materials entails the use of a certain low work function crystallographic direction, such as, for example, (100), (210), and (310). These materials do not naturally facet because of their refractory nature. The disclosed electron source made from transition metal carbide material is especially useful when installed in a scanning electron microscope (SEM) performing advanced imaging applications that require a high brightness, high beam current source.
