  • Schottky junction si nanowire field-effect bio-sensor/molecule detector
    Patent number: 8859316
    Abstract: A Schottky junction silicon nanowire field-effect biosensor/molecule detector with a nanowire thickness of 10 nanometer or less and an aligned source/drain workfunction for increased sensitivity. The nanowire channel is coated with a surface treatment to which a molecule of interest absorbs, which modulates the conductivity of the channel between the Schottky junctions sufficiently to qualitatively and quantitatively measure the presence and amount of the molecule.
