Ultraschnelle Kontrolle über Elektronenpulse

Physiker der Universität Göttingen steuern den Stromfluss in Nanostrukturen mit Terahertz-Feldern

(PresseBox) (Göttingen, )
Die rasant steigende Leistungsfähigkeit moderner Elektronik, beispielsweise in Smartphones, basiert auf immer kleineren und schnelleren Computerchips. Forscher der Universität Göttingen haben an metallischen Nanospitzen nun erstmals eine aktive Kontrolle des Stroms bei Terahertz-Frequenzen - 1000 Milliarden Schaltzyklen pro Sekunde - gezeigt. Derzeit wird der Takt von Computer-Prozessoren in Gigahertz angegeben, was einer Milliarde Schaltzyklen pro Sekunde entspricht. Um zukünftig in den Terahertz-Bereich vorzustoßen, bedarf es gänzlich neuer Technologien, die zwangsläufig von der Elektronik zur Optik führen. Neuartige Konzepte aus der sogenannten Lichtwellenelektronik, mit denen die Göttinger Forscher arbeiten, nutzen kontrollierte Lichtfelder und extrem kurze Laserpulse, um Elektronenströme auf der Nanometerskala ag xirsosa.
