    摘要： A junction, such as a Schottky junction, is formed between a conductive electrode (42) and a semiconductor (41). A bias voltage is applied between the conductive electrode (42) and an outward-emission-side electrode (43) formed on the semiconductor (41) at the side opposite to the junction. Upon illumination, photoelectrons are internally emitted in the conductive electrode (42) into the semiconductor (41), transported through the semiconductor (41), and emitted outward from the semiconductor surface, which has been so treated as to reduce the surface barrier height. The semiconductor is semi-insulating, or a p-n junction is formed therein.

    摘要： This invention aims at providing an X-ray apparatus having a stable X-ray output. Since the focus electrode of the X-ray tube of the X-ray apparatus according to this invention maintains a ground potential, the focus diameter of electrons bombarded against a target becomes constant. Hence, the X-ray output emerging from an exit window is stabilized. Since the potential ratio of a cathode to the target is always constant, the electric field distribution between the cathode and the target is stabilized, thereby stabilizing the X-ray output emerging from the exit window.
