Abstract:
PROBLEM TO BE SOLVED: To provide a field emission thin film showing characteristic physical property, with high performance, and capable of manufacturing a flat cathode with high efficiency by using a carbon film showing an ultraviolet ray Raman band having a half band width in a specified range in a specific wave number range. SOLUTION: A carbon film 703 deposited on a substrate 701 of a field emission element has a band in the range of 1578-1620 cm in ultraviolet ray Raman spectrum, and the half band width of 25-165 cm . The element is formed by coating a conductive layer 702 on the substrate 701, then coating a carbon layer 703 thereon. An anode consists of a substrate 704 made of glass or the like, a conductive layer 705 made of indium oxide or the like, and a fluorescent layer 706 for receiving electrons emitted from the carbon layer 703. Electrons are emitted from the carbon layer 703 by the suitable electric field between the anode and a cathode. The thickness of the carbon film is preferable to be 300 nm or less.

PURPOSE:To obtain a field emission type ion source having a stabilize long lifetime by using a material mainly composed of boride of titanium as a needle electrode, and using a material mainly composed of bride of chromium as a storage parts material. CONSTITUTION:A material mainly composed of boride of titanium is used as a needle electrode 1, and a material mainly composed of boride of chromium is used as storage parts 2A, 2B. At this stage, a needle electrode 1 of which tip has a needle point is used. As the material mainly composed of boride of titanium, titanium boride and the mixture of titanium boride and other boride and nitride, for example, titanium boride - boron nitride or the like having a titanium boride content more than 80% is used. As the material mainly composed of boride of chromium, chrome boride and the mixture of chromium boride and other boride and nitride, for example, such as the mixture of chromium boride - molybdenum boride or the like having a chromium boride content more than 80% is used. A field emission type ion source having a stable and practical lifetime can be thereby obtained.
Abstract:
Provided in the embodiments of the present disclosure are an electron emission apparatus and an electronic apparatus. The electron emission apparatus comprises a fire-resistant container and a heating power supply, the fire-resistant container being provided with a cavity part, the cavity part having a certain degree of vacuum, an electron emission material being arranged in the cavity part, at least one through hole being formed in the bottom of the fire-resistant container, and after being melted by heating, the electron emission material passing through the through hole so as to have an arc-shaped outwards-convex liquid surface and to emit electrons outwards. The embodiments of the present disclosure have a relatively good electron field emission effect and a high degree of product structure consistency, and achieve easy commissioning. The service life of the electron emission apparatus is in direct proportion to the mass of the accommodated electron emission material, so that the service life of the disclosed electronic apparatus can be remarkably prolonged compared with that of a traditional thermal field emission or cold field emission filament, thereby meeting the use requirements of an electron beam exposure machine, a scanning electron microscope, a transmission electron microscope and other X-ray sources.

Abstract:
In the method of the present invention, electrostatic fields (20) are used to induce heat pumping action of a working fluid (18). A plurality of heat pipes with no moving parts are used. The operation of one pump enhances the operation of the next. The method of the present invention is conducive to devices of a wide range of scales. Furthermore, operation at partial power levels is practicable, and precise control of temperature possible. Control is further enhanced by the addition or removal of further units to the system. Reliability should be enhanced, and peak power demands reduced. Wide selection of possible working fluids (18) allows for the elimination of environmentally harmful halocarbons. In one embodiment of the present invention, chemical working fluids are eliminated entirely. In another embodiment, supercooled fluids such as liquid helium may be used while eliminating the wastage commonly encountered using such fluids.
