Zijing Zhao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transistors with switchable polarity and non-volatile configurations
    Patent number: 11527648
    Abstract: Transistors with switchable polarity and non-volatile configurations are provided. The transistors include a van der Waals (vdW) semiconductor layer. A ferroelectric layer with local polarization determines the type and concentration of the doping in the vdW semiconductor layer. Local program gates allow application of voltage to set or switch the polarization in the ferroelectric layer in the source and drain regions. Source and drain contacts permit either n-type or p-type transistor operations according to the carrier polarity in the vdW semiconductor layer.
    Type: Grant
    Filed: February 1, 2021
    Date of Patent: December 13, 2022
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Wenjuan Zhu, Kai Xu, Jialun Liu, Zijing Zhao
