    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: The invention relates to a semiconductor, cathode and a camera tube and a display tube, respectively, having such a cathode, based on avalanche breakdown in a p-n junction extending parallel to the surface of the semiconductor body. The released electrons obtain extra energy by means of an accelerating electrode provided on the device. The resulting efficiency increase makes the manufacture of such cathodes in planar silicon technology practical. Since the depletion zone of the p-n junction upon avalanche breakdown does not extend to the surface, the released electrons show a sharp, narrow energy distribution. This makes such cathodes particularly suitable for camera tubes. In addition they find application, for example, in display tubes and flat displays.

    摘要: Flat-panel type picture display device having a luminescent screen and a large number of electron propagation ducts operating by means of electron wall interaction. Electrons are withdrawn from the ducts by means of an addressing system, whereafter these electrons are directed towards desired locations on the luminescent screen. An apertured spacer plate of electrically insulating material for passing electrons is arranged between the addressing system and the screen. To enable large voltage differences to be applied across the dimension of thickness of the spacer plate, the spacer plate is provided with a high-ohmic layer, or with a pattern of a low-ohmic material, or with an equalization layer at one side and with a low-ohmic layer at the other side, and at least the walls of the apertures are preferably coated with a material having a low secondary emission.
