  • Photocathode with nanowires and method of manufacturing such a photocathode
    Patent number: 11043350
    Abstract: The invention discloses a photocathode comprising an amorphous substrate such as a glass substrate (110) presenting an input face that will receive incident photons and a back face opposite the front face. Nanowires (120) made from at least one III-V semiconducting material are deposited on the back face of the substrate and extend from this face in a direction away from the front face. The invention also relates to a method for manufacturing such a photocathode by MBE.
    Type: Grant
    Filed: May 29, 2017
    Date of Patent: June 22, 2021
    Assignees: PHOTONIS FRANCE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE
    Inventors: Claude Alibert, Moustapha Conde, Jean-Christophe Harmand, Théo Jegorel

  • Multiband photocathode and associated detector
    Patent number: 10186405
    Abstract: The invention relates to a photocathode including an input window (210) suitable for receiving a flow of incident photons, and an active layer (230), the active layer consisting of a plurality of elementary layers (2301, 2302) made of semiconductor materials having decreasing forbidden bandwidths in the direction of the flow of incident photons. The surface of the photocathode opposite the input window is structured so that each elementary layer of the active layer has its own photoelectric emission surface (2401, 2402). By choosing the semiconductor materials of the elementary layers, it is possible to obtain an image which has high sensitivity in both the visible spectrum and the near infrared.
