New look for molecular transistors
Abstract:
Theoretical physicists in the US have proposed a new way to make a single-molecule transistor. David Cardamone, Charles Stafford and Sumit Mazumdar at the University of Arizona say the quantum interference effect transistor (QuIET) could be a realistic way to extend existing transistor technology down to the nanoscale. The device modulates the flow of current through a hydrocarbon ring by switching quantum interference "on" and "off".
