Abstract:
An electron emission source includes nano-sized acicular materials and a cracked portion formed in at least one portion of the electron emission source. The acicular materials are exposed between inner walls of the cracked portion. A method for preparing the electron emission source, a field emission device including the electron emission source, and a composition for forming the electron emission source are also provided in the present invention.
Abstract:
An electron emission display comprises: a cathode substrate having at least one electron emission device; a lower partition wall selectively formed in a predetermined region on the cathode substrate; an anode substrate having an image display region corresponding to the electron emission device; and an upper partition wall selectively formed on the anode substrate facing the cathode substrate. The lower and upper partition walls support the cathode and anode substrates, and maintain a predetermined space between the cathode and anode substrates, and the lower and upper partition walls comprise foam glass. With this configuration, a partition wall instead of a spacer is formed by selectively etching the foam glass, and is used for supporting a substrate, thereby eliminating a process of loading the spacer. A method of fabricating the electron emission display comprises steps for forming each of the aforementioned elements, as described above.
Abstract:
Carbon nanotube Schottky barrier photovoltaic cells and methods and apparatus for making the cells are provided. The photovoltaic cells include at least one contact made from a first contact material, at least one contact made from a second contact material and a plurality of photoconducting carbon nanotubes bridging the contacts. A Schottky barrier is formed at the interface between the first contact material and the carbon nanotubes while at the interface between the second contact material and the carbon nanotubes, a Schottky barrier for the opposite carrier is formed, or a small, or no Schottky barrier is formed. It is the Schottky barrier asymmetry that allows the photo-excited electron-hole pairs to escape from the carbon nanotube device.

An ionizer emitter electrode is ideally formed of or at least partially coated with a carbide material, wherein the carbide material is selected from the group consisting of germanium carbide, boron carbide, silicon carbide and silicon-germanium carbide. Alternatively, a corona-producing ionizer emitter electrode is substantially formed of silicon carbide. Alternatively, a corona-producing ionizer emitter electrode is formed of an electrically conductive metal base that is at least partially coated with silicon carbide. Alternatively, a corona-producing ionizer emitter electrode ionizes gas when high voltage is applied thereto, and the emitter electrode is formed substantially of silicon carbide and has a resistivity of less than or equal to about one hundred ohms-centimeter (100 Ω-cm).

In an electrodeless lamp, at least one core assembly is coupled to a tubular lamp envelope. The core assembly includes a lamp envelope protector disposed over an outer surface of the lamp envelope, and a core member surrounding the lamp envelope at a core mounting location such that lamp envelope protector is disposed between the core member and the lamp envelope. The core assembly further includes a coil bobbin coupled to the core member, and a coil wounded around the coil bobbin.
Abstract:
The disclosed subject matter includes a filament electrode that can include a filament coil connected with a pair of lead wires with confidence. It is possible for a fluorescent lamp using the filament electrode to emit light with a wider range while located in a thin tube. The filament electrode can include a pair of connecting pipes, a pair of lead wires located parallel to each other, and a filament coil including two connecting parts. Each of the two connecting parts of the filament coil can attach to respective ends of the pair of lead wires via the pair of connecting pipes via pressure bonding so as not to contact the connecting parts of the filament coil with the ends of the pair of lead wires located in the pair of connecting pipes and so as to align the structures. Thus, the filament electrode can be used even in a thin glass or quartz tube and can provide an effective heat-shield operation.
