Patent ID: 8487340

Claim:
A process for fabricating of optoelectronic devices based on nanowire-type semiconductors having an axial functional structure, in which: nanowires are produced on a substrate, said nanowires being capable of emitting a light beam by themselves and having p-type and n-type zones that are arranged in succession along the axis of the nanowires; a first electrical contact zone is produced on the substrate; and a second electrical contact zone is produced on the nanowires, characterized in that the second electrical contact zone is provided on the periphery of the nanowires and in direct contact with the nanowires, over a defined height (h) thereof and close to their end on the opposite side from said substrate, and also between said nanowires, the nanowires being doped over said defined height (h) with carriers of opposite conductivity to that of the carriers present in the rest of the nanowires and having a waveguide structure, the upper face of the nanowires being exposed so that the emitted light is guided to said upper face through which it is extracted.
