摘要： A radiation source includes a vacuum chamber, means for injecting an optical wave, a cold source for emitting electrons, a power supply, an anode for emitting X-rays, and at least one window through which the X-rays exit. A light source delivers the optical wave, and the cold source includes at least one substrate with a conducting surface and is subjected to an electric field. The cold further includes a photoconductive element in which the current is controlled approximately linearly by the illumination and at least one electron-emitting element, the photoconductive element electrically connected in series between an emitting element and a conducting surface. Current photogenerated in the photoconductive device is equal to that emitted by the emitter or the group of emitters with which it is associated, and the emitted stream of X-rays is approximately linearly dependent on the illumination.

摘要： In an optically controlled cold-cathode electron tube, the emitters 1, of nanometer and/or micron size and of elongate shape, have a structure comprising a first material (4) of sp2-bonding carbon type and a metallic second material (3), said first material being in contact with and surrounding said second material at its top and over the entire length of the emitter or at least part of said length starting from its top toward the base (b). The second material has a plasma frequency substantially equal to or greater than the frequency of the optical control wave.

摘要： A method according to which a layer of a semiconductor material is made on a substrate by growth in a confinement space defined by this substrate and by a confinement layer, this growth being achieved from a seed. The cross-section of the seed, substantially perpendicular to the general direction of growth, possesses a thick central part framed by two thinned lateral parts. The confinement space has the same cross-section as the seed.
