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： 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.
