Molecular Nanoelectronics - Homepage Molecular Nanoelectronics is electronics based on individual molecules, at a scale of one manometer, a billionth of a meter. There is an ever-increasing need for minuscule computers and other devices, which cannot be made so tiny using silicon. It is often stated that nanotechnology will bring some kind of industrial revolution. Even allowing for a great deal of hype, there is no doubt that something important is going on.
Superconductivity allows currents to flow with no dissipation, and with no waste of energy.
Superconductors give technologists the chance vastly to increase the 'integration' or 'density level' of devices and to pack more transistors into any given area. Within, say, a square centimetre, this can mean the difference between l million and l billion transistors. For some time the best candidates for superconducting molecular nanoelectronics were carbon nanotubes. The artificially rolled-up sheets of graphite atoms, exhibit no resistance to electric current at temperatures below 1K when connected to superconductors. A somewhat simpler way of expressing this would be to use the example of a length of copper wire.
