  • Gas sensing diode comprising SiC
    Patent number: 6291838
    Abstract: A diode for sensing hydrogen and hydrocarbons and the process for manufacturing the diode are disclosed. The diode is a Schottky diode which has a palladium chrome contact on the C-face of an n-type 6H Silicon carbide epilayer. The epilayer is grown on the C-face of a 6H silicon carbide substrate. The diode is capable of measuring low concentrations of hydrogen and hydrocarbons at high temperatures, for example, 800° C. The diode is both sensitive and stable at elevated temperatures.
    Type: Grant
    Filed: November 15, 1999
    Date of Patent: September 18, 2001
    Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space Administration
