Abstract

original image

Stromschalter: Nanodrähte des organischen Halbleiters Kupfer-Tetracyanchinodimethan (Cu-TCNQ) wurden durch Abscheidung aus der Gasphase auf eine Vielzahl an Substraten in Mustern aufgebracht. Eine Kreuzungspunkt-Speichereinheit aus einem Netz von Cu-TCNQ-Nanodrähten (siehe Bild) schaltet wiederholt elektrisch zwischen zwei Zuständen, deren Leitfähigkeiten sich um mehr als zwei Größenordnungen unterscheiden.
