Aussie, Finnish Researchers Create a Single-Atom Transistor

ACKyushu writes "Researchers from Helsinki University of Technology (Finland), University of New South Wales (Australia), and University of Melbourne (Australia) have succeeded in building a working transistor whose active region comprises only a single phosphorus atom in silicon. The results have just been published in Nano Letters. The working principles of the device are based on sequential tunneling of single electrons between the phosphorus atom and the source and drain leads of the transistor. The tunneling can be suppressed or allowed by controlling the voltage on a nearby metal electrode with a width of a few tens of nanometers."

    We've had single Atom CPUs for some years now... :)

    Don't overheat those Phosphorous atoms....

    Well, at least this seems to set an ultimate limit to Moore's law, since it's not very easy to go to less than one atom per transistor.

    Yes, a single atom should be small enough for everyone.

    ...Wouldn't that be kinda hard to read?

    Would be designed around a Higgs Boson which would know when to come back from the future and switch with no gate delay...

    I'm guessing that'd be a Times New Roman 0.0000001 pt font then? Damn, I left my scanning electron reading glasses at home today.
