Abstract: There is provided a diamond n-type semiconductor whose carrier concentration change amount is sufficiently reduced in a wide temperature range. The diamond n-type semiconductor includes a diamond substrate and a diamond semiconductor formed on the main surface of the diamond substrate and judged to be n-type. The diamond semiconductor has a carrier concentration (electron concentration) temperature dependency showing a negative correlation and a hole coefficient temperature dependency showing a positive correlation at a part of the temperature range where it is judged to be n-type. The diamond n-type semiconductor having such characteristics can be obtained, for example, by forming a diamond semiconductor doped with a plenty of donor element while introducing impurities other than the donor element into the diamond substrate.

Abstract: A process for producing an n-type semiconductor diamond characterized in that a single crystal of diamond containing 10 ppm or more of N is implanted with ions so as to contain 10 ppm or above of Li, or a single crystal of diamond is implanted with Li and N ions such that the ion implantation depths where the concentrations of Li and N are 10 ppm or above after ion implantation overlap each other to produce a diamond containing Li and N, and then the diamond is heat treated in a temperature range at least 800°C and less than 1800°C thus activating Li and N electrically and restoring the crystal structure of diamond. The n-type semiconductor diamond contains 10 ppm or more of Li and N, respectively, at the same depth from the crystal surface and has a sheet resistance of 107Omega/□ or less.

Abstract: Disclosed is an electron emitter which is smaller in size, lower in operating voltage, and high in efficiency than the conventional ones. Also disclosed is an electron beam source using such an electron emitter. The electron emitter comprises a light- emitting element for irradiating a cathode with light, and at least electron-emitting surface of the cathode is composed of diamond. By having such a structure, the voltage for extracting electrons can be greatly lowered in this electron emitter than the conventional ones. Namely, there is obtained a small-sized electron emitter which can be operated at low voltage. The above-mentioned light-emitting element is preferably formed integrally with the cathode. The light-emitting element and the electrode are preferably composed of diamond. Further, it is desirable that the electron-emitting surface of the cathode is composed of an n-type or p-type diamond semiconductor.
