  • Modification of infrared reflectivity using silicon dioxide thin films derived from silsesquixane resins
    Publication number: 20030134136
    Abstract: Changes in the infrared reflection spectrum of a thin film of silica-like resinous material sandwiched between metal electrodes can be induced by applying an electric potential to a top electrode which is semitransparent. Characteristic infrared absorption lines change in proportion to a small electric current flowing through the material. These changes occur with response times of the order of seconds, and show time constants of the order of minutes to reach stationary values.
    Type: Application
    Filed: January 30, 2003
    Publication date: July 17, 2003
    Applicant: The Regents of the University of Michigan
    Inventors: Mark Angelo Biscotto, Mark Monroe Banaszak Holl, Bradford Grant Orr, Udo C. Pernisz
