摘要： A display device comprises a light guide and a movable element. By locally exerting a force on the movable element by means of selection means, optical contact between the movable element and the light guide can be brought about. Light emanates from the display device at the locations where optical contact takes place. Measures are taken to employ the force exerted by the selection means as efficiently as possible. This can be achieved by making the force act at the location where the optical contact takes place and/or by reducing other adhesive forces (caused, inter alia, by differences in pressure, static charging, surface stresses, van der Waals' forces and/or chemical forces).

摘要： By providing an intrinsic semiconductor region in a reverse biased junction cathode between an n-type surface region and a p-type zone, a maximum field is present over the intrinsic region in the operating condition. The efficiency of the cathode is increased because avalanche multiplication can now occur over a greater distance, while in addition electrons to be emitted at a sufficient energy are generated by means of tunneling.

摘要： An electron source having a rapid response time comprises at least one n-p-n structure (and possibly an array of said n-p-n structure) formed in a silicon or other semiconductor body (10) by a p-type first region (1) between n-type second and third regions (2 and 3). Electrons (24) are generated in the n-p-n structure (2,1,3) for emission into free space (20) from a surface area (4) of the body (10) after flowing from the second region (2) through the first and third regions (1 and 3). The n-p-n structure (2,1,3) has electrode connections (12 and 13) only to the n-type second and third regions (2 and 3). The first region (1) provides a barrier region restricting the flow of electrons from the second region (2) to the third region (3) until a potential difference (V) is applied between the electrode connections (12 and 13) to bias the third region (3) positive with respect to the second region (2) and to establish a supply of hot electrons (24) injected into the third region (3) with sufficient energy to overcome the potential barrier present between the surface area (4) and free space (20). The barrier region (1) forms depletion layers with both the n-type second and third regions (2 and b 3) and is depleted of holes by the merging together of these depletion layers at least when the potential difference (V) is applied to establish said supply of hot electrons (24). The n-p-n structure can be provided in a mesa portion (9) of the body (10) at a window in an insulating layer (11) so as to form a compact arrangement having very low associated capacitances. The electron sources may be used in cathode-ray tubes, display devices and even electron lithography equipment.

摘要： An electron beam apparatus comprising a semiconductor electron emitter whose emissive surface dimensions are determined by dimensions of a p-n junction provided in the semiconductor element. By optimizing the dimensions of the emissive surface in relation to the electron-optical properties of the apparatus, an emitter is realized which combines optimum beam formation or imaging with a sufficiently large beam current and a high beam current density as required by the apparatus.

摘要： An electron-emitting surface is provided with a material reducing the electron work function, which is obtained from a suitable reaction. The reaction mixture or the product to be decomposed, for example CsN.sub.3, is present in a surface depression of a semiconductor body, while one or more pn junctions act as a heating diode. Upon heating, cesium is released and deposited on the electron-emitting surface.

摘要： In order to reduce object contamination during the examination or machining of the object in an electron beam apparatus, an anti-contamination diaphragm is provided in place of the customary diaphragm. The anti-contamination diaphragm has a central aperture which corresponds to a customary diaphragm aperture, and a concentric annular aperture for transmitting a non-paraxial hollow beam which irradiates a ring around the paraxial focus on the object. The conical hollow anti-contamination beam forms a barrier against contaminating residual gas molecules, notably hydrocarbon molecules.
