What is the different behavior of circuits when the wires are only a few atoms wide?

    There are limits of fabrication processes near the 1-10 nm region, and there's the new and different behavior of circuitry when the wires are only a few atoms wide.

    What I would like to know is what exactly is the new behavior?

    Well, if the wires are too close, electrons can tunnel between them. With such small wires, the whole current is carried by a few electrons.
