Erstmals Perowskit-LED aus dem Drucker - auf dem Weg zu einem neuen Standard für die Elektronik

(PresseBox) (Berlin, )
Einem Team von Forschern des Helmholtz-Zentrum Berlin (HZB) und der Humboldt-Universität zu Berlin ist es zum ersten Mal gelungen, Leuchtdioden (LEDs) aus einem hybriden Perowskit-Halbleitermaterial per Tintenstrahldruck herzustellen. Das Tor zu einer breiten Anwendung solcher Materialien in vielerlei elektronischen Bauelementen ist damit geöffnet. Der Durchbruch gelang den Wissenschaftlern mithilfe eines Tricks: dem „Impfen“ der Oberfläche mit bestimmen Kristallen.

Die Mikroelektronik ist geprägt durch verschiedene funktionelle Materialien, deren Eigenschaften sie für bestimmte Anwendungen auszeichnen. So werden Transistoren und Datenspeicher aus Silizium gefertigt, und auch die meisten photovoltaischen Zellen für die Stromgewinnung aus Sonnenlicht bestehen aus diesem Halbleitermaterial.
