Mehr Power durch Goldlamellen

Forschungsteam entwickelt neues Materialsystem zur Umwandlung und Erzeugung von Terahertz-Wellen

(PresseBox) (Freiberg, )
Terahertz-Licht liegt im elektromagnetischen Spektrum zwischen Infrarotstrahlung und Mikrowellen. Es bietet enorme Potenziale für die Technik von Morgen: Unter anderem könnte es extrem schnelle Mobilfunk-Verbindungen und WLAN-Netze Wirklichkeit werden lassen, etwa als möglicher Nachfolger des 5G-Mobilfunkstandards. Um den dafür nötigen Übergang vom Gigahertz- in den Terahertz-Frequenzbereich vollziehen zu können, mangelt es bislang an effizienten Quellen und Konvertern. Ein deutsch-spanisches Forschungsteam mit Beteiligung des Helmholtz-Zentrums Dresden-Rossendorf (HZDR) hat nun ein Materialsystem entwickelt, mit dem sich Terahertz-Pulse deutlich effektiver erzeugen lassen als bisher. Es basiert auf Graphen, also superflachem Kohlenstoff, das mit einer metallischen Lamellenstruktur beschichtet ist. Die Arbeitsgruppe stellt ihre Ergebnisse jd Wybyprvnpom MDV Iqbx cnq (IHZ: 20.9003/iumbrmw.0g05554).
