Direkter Sprung ins Terahertz

Dirac-Materialien ermöglichen effiziente Signalumwandlung bei Raumtemperatur

(PresseBox) (Freiberg, )
Highspeed-Internet, autonomes Fahren, Internet der Dinge: Datenströme wachsen weltweit in rasantem Tempo. Doch klassische Funktechnologien stoßen an ihre Grenzen: Je höher die Datenrate, desto schneller müssen Signale übertragen werden. Forschende des Helmholtz-Zentrums Dresden-Rossendorf (HZDR) haben nun gezeigt (DOI: 10.1038/s42005-025-02273-0), dass sich schwache Funksignale mit einem nur wenige Dutzend Nanometer dünnen Material effizient in deutlich höhere Frequenzen umwandeln lassen. Und das sogar bei Raumtemperatur. Die Ergebnisse eröffnen Perspektiven für künftige Mobilfunkgenerationen und hochauflösende Sensorik.

Je mehr Daten gleichzeitig übertragen werden sollen, umso höher muss die verwendete Trägerfrequenz sein. Das führt dazu, dass die Forschung mittlerweile bis in den Terahertz-Bereich vordringt. Dieses
