    摘要： An electron emitting element (1) includes a substrate (2), an upper electrode (3), and a fine particle layer (4) sandwiched between the substrate (2) and the upper electrode (3). The fine particle layer (4) includes metal fine particles (6) with high resistance to oxidation, and insulating fine particles (5) larger in size than the metal fine particles (6). The electron emitting element (1) can steadily emit electrons not only in vacuum but also in the atmosphere. Further, the electron emitting element (1) can work without electric discharge so that harmful substances such as ozone, NOx, or the like are scarcely generated. Accordingly, degradation of the electron emitting element (1) due to oxidation does not occur. Therefore, the electron emitting element (1) has a long life and can steadily work continuously for a long period of time even in the atmosphere.

    摘要： A heat exchanger (1) includes: a heat sink (3) which is in contact with a heating element (2); and an electron emitting element (4) which is provided so as to be separated from the heat sink (3) by a space and which provides electrons to the heat sink (3) via air in the space. The electron emitting element (4) includes: an electrode substrate (7); a thin-film electrode (9); a power supply (10) which applies a voltage between the electrode substrate (7) and the thin-film electrode (8); and an electron acceleration layer (8) which accelerates the electrons inside itself in response to the voltage applied by the power supply (10) so that the electrons are emitted from the thin-film electrode (9). The electron acceleration layer (8) is made at least partially of an insulating material. As a result, the heat exchanger (1) has a heat exchange capability which can be maintained and improved independently of a structure in which electric field concentration tends to occur.

    摘要： An electron emitting element of the present invention includes an electron acceleration layer provided between an electrode substrate and a thin-film electrode, which electron acceleration layer includes (a) conductive fine particles and (b) insulating fine particles having an average particle diameter greater than that of the conductive fine particles. The electron emitting element satisfies the following relational expression: 0.3x+3.9≦y≦75, where x (nm) is an average particle diameter of the insulating fine particles, and y (nm) is a thickness of the thin-film electrode 3. Such a configuration allows modification of the thickness of the thin-film electrode with respect to the size of the insulating particles, thereby ensuring electrical conduction and allowing sufficient current to flow inside the element. As a result, stable emission of ballistic electrons from the thin-film electrode is possible.

    摘要： A light emitting element of the present invention includes an electrode substrate; a thin-film electrode; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode. In the electron acceleration layer, as a result of a voltage applied between the electrode substrate and the thin-film electrode, electrons are accelerated so as to be turned into hot electrons. The hot electrons excite surfaces of the silicon fine particles contained in the electron acceleration layer so that the surfaces of the silicon fine particles emit light. Such a light emitting element of the present invention is a novel light emitting element, which has not been achieved by the conventional techniques. That is, the light emitting element of the present invention is able to (i) be produced by using a silicon material, which is available at low price, through a simple production method, and (ii) efficiently emit light.
