COLD CATHODE SEMICONDUCTOR DEVICE

摘要

1 PHN 9025 The invention relates to a semiconductor cathode based on avalanche breakdown in the p-n junction. The released electrons obtain extra energy by means of an accelerating electrode provided on the device. The achieved efficiency increase makes the manufacture of such cathodes in planar silicon technology sensible. Said cathodes are applied, for example, in cathode ray tube, flat displays, pick-up tubes and electron lithography.
