<p>A semiconductor cold-cathode device (1) for emitting electrons has an integral structure composed of a semiconductor (2) between a first electrode (3) and a second electrode (4). A collector electrode (6) is arranged opposite the semiconductor (2A) placed between the first electrode (3) and the second electrode (4). The first electrode (3) is connected with the negative terminal of a voltage supply (8) connected in series with a collector supply (7). The collector electrode (6) is connected with the positive terminal of the collector supply. The second electrode (4) is connected with the positive terminal of the voltage supply (8). The semiconductor cold-cathode device efficiently emits electrons, and it can be manufactured easily.</p> |
