摘要： Vertical field emission devices are described with very small cathode to anode separations. Preferred cathodes have sharp edge emitters extending, outward perpendicular to the surface of the underlying substrate. These sharp edge emitters are produced within planar photolithography by coating sacrificial conformal walls and anisotropic etching. Microencapsulation is used to produce a sealed cavity at low pressure which includes the space between the anode and cathode. The field emission components can be adapted for the production of light emitting, field emission diodes. The individual cathode emitters can be integrated with solid state components on the substrate with each cathode being independently addressable. Arrays of closely packed light emitting, field emission diodes of the present invention are particularly suitable for use in displays. These displays would be useful for flat-panel computer displays and high definition television.
摘要翻译：用非常小的阴极与阳极分离来描述垂直场致发射器件。优选的阴极具有尖锐的边缘发射体，其垂直于下面的衬底的表面向外延伸。这些锋利的边缘发射器是通过涂覆牺牲保形壁和各向异性蚀刻在平面光刻中产生的。微囊化用于在低压下产生包括阳极和阴极之间的空间的密封空腔。场致发射元件可以适用于制造发光场发射二极管。各个阴极发射器可以与衬底上的固态组件集成，每个阴极可独立寻址。本发明的紧密堆积的发光场发射二极管阵列特别适用于显示器。这些显示器对于平板电脑显示器和高分辨率电视将是有用的。

摘要： An improved electron tube is provided which eliminates the need for a heated electron source and affords simplified construction. The tube, a high vacuum tube, is capable of operating over an extended range of electrical potentials. The electron tube operates on the principle of electric field effect emission for the electron source, requiring neither gas, vapor nor a heated electrode in its envelope. Two active elements, an emitter and a collector, are enclosed in an evacuated chamber with outside connections to each element. The collector is a metal plate and the emitter is an oxide-metal composite which contains a very large number of metal filaments embedded in an insulating oxide matrix. The number of filaments normally exceed one million per square centimeter of exposed surface, having ends connected on the back side to a conducting plate for external connection.

摘要： To increase selectively the electron emission from a cathode, a control grid is placed above the cathode and osmium or iridium is evaporated through the openings of the grid onto the cathode. On the resulting cathode the coated regions provide a value of work function which is lower than that of the uncoated regions.
摘要翻译：为了选择性地增加来自阴极的电子发射，将控制栅格放置在阴极上方，并且锇或铱通过栅格的开口蒸发到阴极上。在得到的阴极上，涂覆区域提供比未涂覆区域低的功函数值。
