    摘要: It is possible to provide an electron emission cathode, an electron emission source having a high-luminance and narrow energy width by using diamond and an electronic device using them. The diamond electron discharge cathode has a monocrystal diamond at least at a part of it. The diamond electron emission cathode has a columnar shape having a sharpened portion at a part of the electron emission section and is formed by at least two types of semiconductor having different electric characteristics. One of the types constituting the semiconductor is an n-type semiconductor containing 2 × 1015 cm-3 of n-type impurities or above and the other type is a p-type semiconductor containing 2 × 1015 cm-3 of p-type impurities or above. The p-type semiconductor is in contact with the n-type semiconductor and negative potential is applied to the n-type semiconductor with respect to the p-type semiconductor so that electrons flow from the n-type semiconductor to the p-type semiconductor by a pair of current introduction terminals, and the n-type semiconductor contains such a component that the electrons flow into the electron emission unit.

    摘要: There is disclosed a method of controlling an electron gun without causing decreases in brightness of the electron beam if a current-limiting aperture cannot be used. The electron gun (10) has a cathode (11), a Wehnelt electrode (12), a control electrode (13), an anode (14), and a controller (22). The Wehnelt electrode (12) has a first opening in which the tip of the cathode is inserted, and focuses thermal electrons emitted from the tip of the cathode (11). The thermal electrons emitted from the tip of the cathode (11) are caused to pass into a second opening by the control electrode (13). The anode (14) accelerates the thermal electrons emitted from the cathode (11) such that the thermal electrons passed through the second opening pass through a third opening and impinge as an electron beam (B1) on a powdered sample (8). The controller (22) sets the bias voltage and the control voltage based on combination conditions of the bias voltage and control voltage to maintain the brightness of the beam constant.
