Bye bye microprocessor, hello nanoprocessor! Well… sort of. The proof-of-concept demonstration used nanowires to perform very basic logic functions. But it isn’t smaller than conventional technology (yet). A more exciting aspect than size may be power consumption: the germanium nanowire mesh is much more energy efficient than silicon microprocessors.

And the comment in Nature: Criss-crossed nanowires can compute.
