    Abstract: Provided is a piezoelectric-film-type electron emitter of high durability exhibiting suppressed reduction in electron emission quantity, which reduction would otherwise occur with repeated use of the electron emitter. The electron emitter includes a substrate, a lower electrode, an emitter layer, and an upper electrode. The upper electrode has a plurality of openings, and an emitter section located on the top surface of the emitter layer is exposed through the openings to a reduced-pressure atmosphere. The electron emitter is configured so that when a pulse drive voltage Va is applied between the lower electrode and the upper electrode, electrons are accumulated on the emitter section, and then the electrons are emitted toward the reduced-pressure atmosphere. The emitter layer contains a primary component (i.e., a ferroelectric composition) and an additional component. The additional component contains a transition metal oxide of high oxidation number which can serve as an oxidizing agent by being converted into an oxide of the transition metal of lower oxidation number.

    Abstract: An electron-emitting device, for example as used in a field emissive display device, includes a barrier layer between an emitter electrode structure and a catalyst layer, upon which microstructures of carbon nanotubes are formed. The barrier layer may act as an anti diffusion layer between the catalyst layer and, for example, a resistive layer of the emitter electrode structure. In this way, the catalyst layer may be prevented from diffusing into the resistive layer during the growing of the carbon nanotubes or other electron-emissive elements. The barrier layer may also enhance the adhesion characteristics of the catalyst layer to improve the uniformity of growth of the electron-emissive elements with the catalyst layer.
