Abstract: A field-emission type switching device includes a substrate formed with a recess having a straight edge and serrated edge opposite to the straight edge. A gate electrode is formed at the bottom of the recess. An emitter electrode is provided over the substrate and formed with a serrated edge which is slightly off alignment with the serrate edge of the recess so as to provide an emitter overhanging portion overhanging the recess. Similarly, a collector electrode is provided over the substrate and formed with a straight edge which is slightly off alignment with the straight edge of the recess so as to provide a collector overhanging portion overhanging the recess. The emitter and collector electrodes are disposed in one plane and the gate electrode is disposed in another plane below the one plane.

Abstract: The shape of an electron beam emitted from an LaB.sub.6 single crystal cathode can be controlled directly by shaping the cathode tip itself. The LaB.sub.6 cathode is provided with a flat top surface which is substantially perpendicular to the emitted beam direction and which corresponds in shape to the shape of the beam desired. For a square beam the flat top surface is square in shape. The size of the shaped top surface and operating conditions are arranged such that emission of electrons occurs over substantially the entire shaped top surface with minimum emission from side regions of the tip adjacent to this shaped surface. In order to maximize emission from the shaped top surface, a crystallographic orientation is selected such that the shaped top surface exposes a relatively low work function crystal plane. Emission from side regions of the tip adjacent to the shaped high emission surface may be reduced by orienting such side regions very obliquely to the emitted beam axis. The side regions may also be flat surfaces, in which case emission from these flat side surfaces may be reduced by orienting the flat side surfaces such that they expose relatively high work function crystal plane.

Abstract translation: 从LaB6单晶阴极发射的电子束的形状可以通过使阴极端头本身成形来直接控制。 LaB6阴极设置有平坦的顶表面，该平坦顶表面基本上垂直于发射的光束方向，并且其形状对应于所需光束的形状。 对于方形梁，平坦的顶面是正方形的。 成形的顶表面和操作条件的大小被布置成使得电子的发射在基本上整个成形的顶部表面上发生，其中尖端的邻近该成形表面的侧面区域具有最小的发射。 为了最大化来自成形顶表面的发射，选择晶体取向，使得成形顶表面暴露相对较低的功函数晶面。 可以通过使这样的侧面区域非常倾斜地相对于发射的射束轴线定向，来减少邻近成形的高发射表面的尖端的侧面区域的发射。 侧面区域也可以是平坦表面，在这种情况下，可以通过使平坦侧表面定向使得它们暴露相对较高的功函数晶面而减小这些平坦侧表面的发射。

Abstract: Disclosed is an electron-beam cathode which emits electrons with a low work function over a relatively wide range of temperature and pressure. The cathode is comprised of single crystal tungsten having zirconium and oxygen dopant atoms within the bulk thereof. This cathode is formed by the steps of attaching zirconium to a portion of the surface of single crystal tungsten, and heating the tungsten with the zirconium attached thereto in an atmosphere of oxygen to diffuse the zirconium and the oxygen into the bulk of the tungsten.

Abstract: A storage system for the mass recording and readout of digital data with ultra high resolution. An electron beam structure is provided for forming a beam of extremely small focused spot diameter, on the order of 0.1 microns, and high current density capability, on the order of 1,000 amperes per sq. cm., which records data by scanning over defined areas of the storage medium surface and micromachining elemental portions of said medium as a function of beam modulation. Readout may be subsequently accomplished by similarly scanning the beam at reduced power density and detecting electrons that have been transmitted by or reflected from the storage medium.
