Nano-Türme feuern einzelne Photonen ab

(PresseBox) (Würzburg, )
Weltweit führend sind Würzburger Physiker bei der Herstellung ausgefeilter Nanostrukturen. Die Früchte ihrer Forschung könnten künftig eine abhörsichere Datenübertragung möglich machen.

Winzige Türmchen aus Halbleitermaterial sind es, die am Lehrstuhl für Technische Physik der Universität Würzburg Gestalt annehmen. Ihre Höhe beträgt etwa zehn Mikrometer, ihr Durchmesser nur ein bis zwei Mikrometer - das Haar eines Menschen ist etwa hundert Mal dicker.

In den Türmchen stecken spezielle Strukturen, die Licht abgeben können: Es sind so genannte Quantenpunkte, deren elektronische und optische Eigenschaften sich bei der Herstellung maßschneidern lassen. Quantenpunkte besitzen - ähnlich wie einzelne Atome - exakt definierte Energiezustände. Darum können jcq Mkvvdubx (Kvnibglwsphjp) ynk dgafs sfuttwgqaoix Abrfaln lfagsqcyl.
