Goldene Nanoelektronik

Weg frei für Mikroprozessoren aus Gold-Nanopartikeln

(PresseBox) (Freiburg, )
Normalerweise müssen Metallpartikel von einer Schutzschicht - den Liganden - umgeben sein, damit sie nicht aneinander haften. Jetzt aber hat das Forschungsteam um den Chemiker Dr. Stijn F.L. Mertens der Universität Bern herausgefunden, dass kleine Goldpartikel in ionischer Flüssigkeit auch ohne Liganden quantisiertes Ladungsverhalten zeigen. Quantisiert heißt, es können einzelne Ladungen kontrolliert auf eine extrem kleine Struktur aufgebracht und wieder heruntergeholt werden. Die Schutzfunktion übernimmt dabei die ionische Flüssigkeit.

Den theoretischen Hintergrund zum Projekt lieferten die Physiker Dr. Michael Walter und Alexander Held vom Freiburger Materialforschungszentrum der Albert-Ludwigs-Universität. Die beiden Wissenschaftler berechneten die Eigenschaften der Goldpartikel, indem sie durch ein Tieemacewktttqfqa ffg Elasjnuwqoigtz vue Ziecjxq' Pyoa taxrseuttv.
