摘要： A method for producing a display device comprising several pixels. The production of each pixel includes producing a stack forming p-i-n junctions of semiconductors corresponding to compounds comprising nitrogen and aluminium and/or gallium and/or indium atoms; implanting first, second and third rare earth ions respectively in first, second and third parts of a nest portion, through masks comprising first, second and third openings disposed respectively facing first, second and third regions of the stack respectively forming first, second and third light emission regions.

摘要： A light-emitting diode may include: a first n-doped semiconductor portion; a second p-doped semiconductor portion; an active zone disposed between the first and second portions and including at least one emitting semiconductor portion; a layer that is electrically conductive and optically transparent to at least one wavelength of the UV range configured to be emitted from the emitting portion, the layer being such that the second portion is disposed between the layer and the active zone. The semiconductors of the first portion and of the emitting portion may include compounds including nitrogen atoms as well as atoms of aluminum and/or of gallium. The semiconductor of the second portion may include AlX2Ga(1-X2-Y2)InY2N that is p-doped with magnesium atoms, wherein X2>0, Y2>0, and X2+Y2

摘要： A process for producing light-emitting diodes includes producing a first segment made of inorganic semiconductor doped with a first conductivity type; producing, on a first region of the first segment and through a mask, a first emitting segment made of inorganic semiconductor; moving the mask; producing, on a second region of the first segment, a second emitting segment made of inorganic semiconductor; and producing, at least on the first and second emitting segments, a segment made of inorganic semiconductor doped with a second conductivity type. The chemical compositions of the first and second emitting segments are different from each other and such that their bandgaps are narrower than or equal to those of the segments made of doped inorganic semiconductor.
