  • Embedded metal nanocrystals
    Patent number: 6743709
    Abstract: Low resistance metal/semiconductor and metal/insulator contacts incorporate metal nanocrystals embedded in another metal having a different work function. The contacts are fabricated by placing a wetting layer of a first metal on a substrate, which may be a semiconductor or an insulator and then heating to form nanocrystals on the semiconductor or insulator surface. A second metal having a different work function than the first is then deposited on the surface so that the nanocrystals are embedded in the second material.
    Type: Grant
    Filed: August 5, 2002
    Date of Patent: June 1, 2004
    Assignee: Cornell Research Foundation, Inc.
    Inventors: Edwin C. Kan, Zengtao Liu, Venkatasubraman Narayanan
