In zwei Dimensionen leuchten Elektronen schneller

Forscher weisen erstaunliches Verhalten einzelner Atomlagen nach

(PresseBox) (Regensburg, )
Physiker der Universitäten Regensburg und Münster konnten erstmals beobachten, wie sich Elektronen in einer ultradünnen Festkörperschicht zu atomähnlichen Teilchen binden und dabei Licht in Rekordgeschwindigkeit emittieren. Die Ergebnisse wurden jetzt in der renommierten Fachzeitschrift "Nature Materials" veröffentlicht (DOI 10.1038/nmat4356).

Seit kurzem kann die Wissenschaft Materialien herstellen, die aus einer einzigen Atomlage bestehen. Neben Graphen - einer Monolage aus Graphit - funktioniert dies inzwischen auch mit sogenannten Übergangsmetall-Dichalkogeniden wie Wolframdiselenid. In Monolagen können sich Elektronen nur zweidimensional in der Ebene bewegen. Das verleiht den ultradünnen Materialien einzigartige Eigenschaften, die künftig die Elektronik und Optoelektronik revolutionieren könnten.
