  • Segregation resistant perovskite oxides with surface modification
    Patent number: 11179682
    Abstract: A method and a composition to stabilize the surface cation chemistry of the perovskite or related oxides, and thus, to minimize or completely avoid the detrimental segregation and phase separation of dopant cations at the surface can include modifying the surface with more oxidizable metal cations and/or more oxidizable metal oxides, thereby reducing the oxygen vacancy concentration at the very surface.
    Type: Grant
    Filed: March 30, 2016
    Date of Patent: November 23, 2021
    Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGY
    Inventors: Bilge Yildiz, Nikolai Tsvetkov, Qiyang Lu
