Dabei benutzten sie ein innovatives Verfahren, indem sie einzelne Moleküle auf einer atomaren Oberfläche wie Dominosteine bewegten. Siehe auch unter: http://www.almaden.ibm.com/st/exploratory_technology/mc/index.shtml 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 toppling a single domino can cause a large pattern to fall in sequence. The scientists then designed and created tiny structures that demonstrated the fundamental digital-logic OR and AND functions, data storage and retrieval, and the "wiring" necessary to connect them into functioning computing circuitry.
