  • Water soluble oxide liftoff layers for GaAs photovoltaics
    Patent number: 11621365
    Abstract: Disclosed herein are compositions, methods and devices that allow for water-soluble epitaxial lift-off of III-V. Epitaxial growth of STO/SAO templates on STO (001) and Ge (001) substrates were demonstrated. Partially epitaxial GaAs growth was achieved on STO/SAO/STO substrate templates.
    Type: Grant
    Filed: June 17, 2020
    Date of Patent: April 4, 2023
    Assignee: Alliance for Sustainable Energy, LLC
    Inventor: Andrew Gordon Norman
  • Methods of exfoliating single crystal materials
    Patent number: 11302531
    Abstract: Disclosed herein are methods for exfoliation of single crystals allowing for growth of high crystalline quality on the exfoliated surfaces for III-V photovoltaics. Also disclosed herein are methods for growing GaAs (111) on layered-2D Bi2Se3 (0001) substrates in an MOCVD reactor.
