  • Quantum interference effect transistor (QuIET)
    Patent number: 7786472
    Abstract: A molecular-based switching device and method for controlling charge transport across a molecule. The molecular-based switching device includes a molecule having first and second nodes in between which destructive quantum interference restricts electrical conduction from the first node to the second node in an off-state, a first electrode connected to the first node and configured to supply charge carriers to the first node, a second electrode connected to the second node and configured to remove the charge carriers from the second node, and a control element configured to reduce coherence in or alter charge transport paths between the first and second nodes so as to reduce existing destructive quantum interference and permit flow of the charge carriers from the first node to the second node.
    Type: Grant
    Filed: March 20, 2007
    Date of Patent: August 31, 2010
    Assignee: Arizona Board of Regents/Behalf of University of Arizona
    Inventors: Charles Allen Stafford, David Michael Cardamone, Sumitendra Mazumdar
