Was Elektronen zum Zittern bringt

Bewegungen in Halbleitern erzeugen Strahlung mit Rekordbandbreite

(PresseBox) (Regensburg, )
Moderne Hochgeschwindigkeitselektronik basiert auf winzigen Halbleiter-Strukturen, in denen Elektronen mit Hilfe von elek­trischen Feldern auf immer höhere Geschwin­dig­kei­ten beschleunigt werden. Bald schon dürften Feldstärken erreicht werden, die zu einer neu­en Klasse von Quantenphänomenen füh­ren. Physiker der Uni­ver­si­täten Regensburg, Mar­burg und Pader­born haben nun nachgewiesen, dass sich Elektronen unter diesen Be­dingungen nicht mehr monoton in eine Richtung bewegen, son­dern extrem schnelle Oszillationen ausführen, die Licht über einen superbreiten Spek­tral­bereich ausstrahlen. Die Ergebnisse wurden in der Fachzeitschrift "Nature Photo­nics" veröffentlicht (DOI: 10.1038/nphoton.2013.349).

Vor 85 Jahren beschrieb Felix Bloch, einer der Väter der modernen Festkörperphysik, die Bewegungen von Elektronen in einem Festkörper mit tojhsxtwghqlznwiypq Govwzy.
