  • Semiconductor heterostructures with wurtzite-type structure on ZnO substrate
    Patent number: 11217663
    Abstract: A process for fabricating a heterostructure made of semiconductor materials having a crystalline structure of wurtzite type, includes the following steps: structuring a surface of a zinc oxide monocrystalline substrate into mesas; depositing by epitaxy at least one layer of semiconductor materials having a crystalline structure of wurtzite type, forming the heterostructure, on top of the structured surface. Heterostructure obtained by such a process. A process for fabricating at least one electronic or optoelectronic device from such a heterostructure is also provided.
    Type: Grant
    Filed: November 15, 2017
    Date of Patent: January 4, 2022
    Assignee: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE
    Inventors: Julien Brault, Mohamed Al Khalfioui, Benjamin Damilano, Jean-Michel Chauveau
