Wegweisende Forschung: Licht auf der Nanoskala schalten

Bayreuther Physiker verwenden Nanostäbchen als schaltbare Nano-Ampeln

(PresseBox) (Bayreuth, )
Mit einem an der Uni Bayreuth entwickelten Verfahren lassen sich Lichtquellen auf der Nanoskala gezielt ein- und ausschalten. Mögliche Anwendungen reichen von der Datenübertragung bis zum Ausmessen elektronischer Zustände.

Metallische Nanopartikel, die nur wenige Millionstel Millimeter lang sind, können als Basis für Lichtquellen genutzt werden, die sich ähnlich wie die Lichter von Ampeln im Straßenverkehr präzise steuern lassen. Dies hat ein Forschungsteam um Prof. Dr. Markus Lippitz, Experimentalphysiker an der Universität Bayreuth, herausgefunden. Das hier entwickelte Verfahren macht es erstmals möglich, Lichtquellen auf der Nanoskala gezielt ein- und auszuschalten. In der Fachzeitschrift "Nature Communications" wurden diese wegweisenden Forschungsergebnisse kürzlich vorgestellt.
