摘要： A field emission cathode that can uniform the number of electrons emitted from each emitter and can prevent a line defect even when a gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode, so that the current supplied from the cathode electrode to the emitter can be controlled. If the emitter is short-circuited with the gate electrode, the increased current density destroys the channel, so that the current supply to the emitter can be stopped.
摘要翻译：场发射阴极可以均匀化从每个发射极发射的电子数，并且即使当栅极与发射极电短路时也可以防止线路缺陷。通过向电流控制电极施加正电压来控制形成在沟道形成电极上的沟道中的电子的移动，从而可以控制从阴极供给到发射极的电流。如果发射极与栅电极短路，则增加的电流密度会破坏通道，从而可以停止对发射极的电流供应。

摘要： An image display device capable of minutely setting the interval between an emitter (6) and a gate (5) with high accuracy and of being driven at a significantly reduced drive voltage with good emission uniformity. Each emitter (6) is provided in a recess in a substrate (2), so that the interval between the emitter (6) and a gate (5) is determined depending upon the thickness of the emitter (6). Thus, the interval can be readily controlled by adjusting or varying the period of time during which the film for the emitter (6) is formed, resulting in a micro-interval of the order of sub-microns between the two components being possible with high accuracy.

摘要： A field emission element including a gate and an emitter and capable of penting any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.

摘要： A field emission cathode capable of reducing an operation voltage and substantially preventing damage of an emitter. An emitter is provided on a substrate. The emitter includes a base and a plurality of rectangular tips projecting from the base. A gate is arranged in a recess formed on the substrate so as to be in proximity to the emitter. A width a of the tips of the emitter and an interval b between the tips are defined to satisfy a relationship of b/a=2. This permits an electric field strength applied to the tips of the emitter to be substantially increased as compared in a conventional field emission cathode of b/a.ltoreq.1, resulting in an operation voltage being reduced and a sufficient amount of emitter current being produced.

摘要： Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.
