摘要： An electron emitting element is of a structure in which a semiconductor layer is formed between an upper electrode and a lower electrode, wherein an organic compound adsorption layer is formed on a semiconductor surface of the semiconductor layer by causing the organic compound to be adsorbed on the semiconductor surface. Herein, the semiconductor layer can be made of silicon or polysilicon and partly or as a whole porous. The absorbed organic compound can be a non-cyclic hydrocarbon, a compound obtained by coupling at least an aldehyde group to a non-cyclic hydrocarbon, or a non-cyclic hydrocarbon having an unsaturated bond. As a result, there can be provided an electron emitting element capable of stably operating in the atmosphere or in a low vacuum even when being operated in the atmosphere or in the low vacuum and an imaging device using the electron emitting element.

摘要： Provided are an electron emitter continuously emitting electrons stably even in the atmosphere, a charger using the electron emitter, and a charging method using the charger. The electron emitter includes a electron emitting element consisting of a first electrode, a second electrode, and a semiconductor layer formed therebetween, and a power supply for alternately applying a positive voltage enabling electron emission and a negative voltage having a polarity opposite to the positive voltage. At least a part of the surface on the first electrode side of the semiconductor layer is formed of a porous semiconductor layer. Electrons captured in the porous semiconductor layer in the course of electron emission with application of a positive voltage disturb electron emission from the electron emitting element. Such electrons, however, are removed by application of a negative voltage.

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.
