IBM researchers have built and operated the world's smallest working computer circuits using an innovative new approach in which individual molecules move across an atomic surface like toppling dominoes.
The new "molecule cascade" technique enabled the IBM scientists to make working digital-logic elements some 260,000 times smaller than those used in today's most advanced semiconductor chips.
The circuits were made by creating a precise pattern of carbon monoxide molecules on a copper surface. Moving a single molecule initiates a cascade of molecule motions, just as ...
