The new phenomenon, called the "quantum mirage" effect, may enable data transfer within future nanoscale electronic circuits too small to use wires. As computer circuit features shrink toward atomic dimensions -- which they have for decades in accordance with Moore's Law -- the behavior of electrons changes from being like particles described by classical physics to being like waves described by quantum mechanics. On such small scales, for example, tiny wires don't conduct electrons as well as classical theory predicts. So quantum analogs for many traditional functions must be available if nanocircuits are to achieve the desired performance advantages of their small size. Some 5,000 times smaller than a human hair, this elliptical ring of 36 cobalt atoms creates a "quantum mirage" that may lead to an efficient way of moving information within future atom-scale circuits and computers Weitere Informationen unter: http://www.research.ibm.com/pics/nanotech/ BU: RUBRIK: Forschung Technologie Fertigung BILDART: Makroaufnahme STICHWORTE: Nanotechnologie, RTM, Kobalt, IBM Research, Rüschlikon,Scanning tunneling microscope, STM, Raster-Tunnel, RTM IBM_NUMMER: 81934 FARBE: farbig FORMAT: Quer ORIGINAL: Digital BILDRECHTE: IBM BILDQUELLE: IBM Almaden Research Center EINGABE: Häßler EXPORTPATH: 26/images/50758043.jpg |
