Patents by Inventor John Marohn

John Marohn 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).

  • Atomic force microscopy apparatus, methods, and applications
    Patent number: 11808783
    Abstract: Atomic force microscopy apparatus and method that enable observing charge generation transients with nanometer spatial resolution and nanosecond to picosecond time resolution, the timescale relevant for studying photo-generated charges in the world's highest efficiency photovoltaic films. The AFM apparatus includes an AFM, a light source for illumination of a sample operatively coupled to the AFM, a voltage source operatively coupled to the AFM, and a control circuitry operatively coupled to the light source and the voltage source. The AFM apparatus improves the time resolution and enables rapid acquisition of photocapacitance transients in a wide array of solar-energy-harvesting materials.
    Type: Grant
    Filed: October 21, 2021
    Date of Patent: November 7, 2023
    Assignee: Cornell University
    Inventors: John Marohn, Sarah Nathan, Ryan Dwyer
