摘要： A semiconductor device for electron emission in a vacuum comprises a stack of two or more semi-conductor layers of N and P type according to sequence N/(P)/N forming a juxtaposition of two head-to-tail NP junctions, in materials belonging to the III-N family, two adjacent layers forming an interface. The semiconductor materials of the layers of the stack close to the vacuum, where the electrons reach a high energy, have a band gap Eg>c/2, where c is the electron affinity of the semiconductor material, the P-type semiconductor layer being obtained partially or completely, by doping impurities of acceptor type or by piezoelectric effect to exhibit a negative fixed charge in any interface between the layers, a positive bias potential applied to the stack supplying, to a fraction of electrons circulating in the stack, the energy needed for emission in the vacuum by an emissive zone of an output layer.

摘要： The disclosure relates to a magneto-optical reading device for multi-track magnetic tapes, including a flat large incident beam directed onto the active part of a magneto-optical read head and reflected by this head onto an array of sensors, characterized in that it includes a correction device able to move the zone of incidence of the beam on the read head in order to keep the beam optimally positioned on the active part of the read head as the latter suffers progressive wear. The invention increases the useful working life of such a reading device.

摘要： A process for producing magnetoresistive transducers, using microlithographic techniques, where the transducers have magnetic metallic multilayers deposited by sputtering or by molecular beam epitaxy, and forming columns whose side walls will be covered with an insulation and whose tops will be free of this insulation, such that a current is able to flow in the magnetoresistive transducers perpendicular to the plane of the layers so as to exploit a phenomenon of perpendicular giant magnetoresistance. This process includes a step of producing, on one surface of a substrate, a stack including a first conductive layer in contact with a substrate and successive magnetic layers and non-magnetic metallic layers constituting a magnetic metallic multilayer in contact with the conductive layer. The process also includes steps of producing a second conductive layer on the magnetic metallic multilayer, producing a first resin mask having the dimensions of a magnetoresistive sensitive element to be produced and etching, around the mask, the second conductive layer and the magnetic metallic multilayer. Subsequently, the process includes steps of depositing an insulation layer removing the resin mask with the insulation layer lying on the resin mask, and forming an electrical contact on the second conductive layer.
