摘要： A porous dielectric material such as silica-based aerogel is used as the dielectric layer 48 between the gate and the cathode on the emitter plate 12 of a field emission device. Aerogel, which can have a relative dielectric constant as low as 1.03, is deposited over the resistive layer 44 of the emitter plate 12. Metal layer 49, functioning as the gate electrode, is subsequently deposited over the aerogel layer 48. The use of aerogel as a gate dielectric reduces power consumption. In a disclosed embodiment, aerogel layer 48 is comprised of sublayers 48a, 48b, and 48c of aerogels of differing densities, thereby providing better adhesion of the aerogel gate dielectric to both the resistive layer 44 and metal layer 49. Methods of fabricating the aerogel gate dielectric are disclosed.

摘要： An improved method of affixing spheres 4 to a foil matrix 2 is described herein. First, a cell sandwich 32 is prepared. This cell sandwich 32 includes spheres 4 mounted on a foil matrix 2 which are disposed between upper and lower pressure pads 34 and 36. The cell sandwich 32 is then heated (e.g., to about 530.degree. C.). The spheres 4 are then affixed to the foil matrix 2 by directing the cell sandwich 32 through a roll press 48 which compresses the heated cell sandwich 32.

摘要： A method and apparatus for forming silicon spheres (40) from irregular-shaped particles (38) for use in solar cells are disclosed. The apparatus (10) generally comprises a vertically aligned cylindrical chamber (12) having an abrasive lining (32) integrally formed therein. The abrasive lining (32) is preferably a silicon carbide material. A gas source (36) is tangentially injected into the chamber (12) to create an gas vortex inside the chamber (12). This vortex induces the repeated collision of the particles (38) against the abrasive lining (32) to eventually form the silicon spheres (40) and simultaneously sizing the silicon spheres (40).

摘要： Semiconductor spheres are arranged within a plastic sheet and laminated between two metal foil layers to make electrical contacts. A portion of each sphere is exposed on one side to allow light entry. The back ohmic contact has a spreading resistance which protects large array configurations from short circuits. Series interconnections of cells, for higher voltage, can be made in the same processing sequence, and are coplanar with the array. All manufacturing steps are completed at temperatures less than 400.degree. C.

摘要： The present invention combines several features to create a novel type of optical telecommunications switching component using microwave waveguides as opposed to the usual methods employing light deflection or digital signal processing. Some of the components of the device include: (1) an optical crossconnect (OXC) which allows any combination of wavelengths to be added or dropped from an element to an optical network, (2) an optical add/drop multiplexer (OADM) which allows any wavelength to be converted to any other, (3) a microwave crossbar switch array optimized for this purpose, and (4) a means for reshaping the exiting signal from the microwave crosspoint switch array without regard to signal format and without need for complex and expensive digital signal processing. The minimal architecture for this functionality is shown to be three N×N microwave crossbar switch arrays.

摘要： The emitter plate 60 of a field emission flat panel display device includes a layer 68 of a resistive material and a mesh-like structure 62 of an electrically conductive material. A conductive plate 78 is also formed on top of resistive coating 68 within the spacing defined by the meshes of conductor 62. Microtip emitters 70, illustratively in the shape of cones, are formed on the upper surface of conductive plate 78. With this configuration, all of the microtip emitters 70 will be at an equal potential by virtue of their electrical connection to conductive plate 78. In one embodiment, a single conductive plate 82 is positioned within each mesh spacing of conductor 80; in another embodiment, four conductive plates 92 are symmetrically positioned within each mesh spacing of conductor 90. Also described is an arrangement of emitter clusters including conductive plates 102 having a plurality of microtip emitters 104 formed thereon, or spaced thereform by a thin layer of resistive material, each cluster adjacent and laterally spaced from a stripe conductor 100 by a region 106 of a resistive material. The conductive stripes 100 are substantially parallel to each other, are spaced from one another by two conductive plates 102, and are joined by bus regions 110 outside the active area of the display.
