Patents by Inventor Ifat Jahangir

Ifat Jahangir 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).

  • Synthesis and fabrication of transition metal dichalcogenide structures
    Patent number: 10777410
    Abstract: Methods of synthesis and fabrication of a transition metal dichalcogenide (TMD) structures are disclosed. A method can include first patterning a transition metal (TM) on a substrate and placing the substrate in a process chamber. Oxygen can be applied to the transition metal on the substrate and a mixture of highly reactive transition metal oxides can be formed and simultaneously thinned down by sublimation. Finally, a chalcogen can be applied to the substrate and a transition metal dichalcogenide structure can be formed.
    Type: Grant
    Filed: February 2, 2018
    Date of Patent: September 15, 2020
    Assignee: University of South Carolina
    Inventors: Ifat Jahangir, Goutam Koley, MVS Chandrashekhar
  • Microcantilever based selective volatile organic compound (VOC) sensors and methods
    Patent number: 10191004
    Abstract: Microcantilevers and systems incorporating the microcantilevers are described that can be utilized to perform selective detection of VOCs. The systems can detect VOCs at temperatures below the auto-ignition temperature of the VOCs and the microcantilevers need not be functionalized with any reactive groups particularly designed for the VOCs to be detected. The microcantilevers are triangular microcantilevers that can be formed of high bandgap semiconductors such as AlGaN/GaN heterojunction semiconductors.
