Neuartiges Hybridmaterial erweist sich als effizienter Fotodetektor

(PresseBox) (Freiberg, )
Digitalkameras, aber auch viele andere elektronische Anwendungen benötigen lichtempfindliche Sensoren. Um den steigenden Bedarf an solchen optoelektronischen Bauteilen zu decken, sucht die Industrie nach neuen Halbleitermaterialien. Diese sollten nicht nur einen möglichst breiten Wellenlängenbereich erfassen, sondern auch preisgünstig sein. Ein in Dresden entwickeltes Hybridmaterial erfüllt beide Anforderungen. Himani Arora, Physik-Doktorandin am Helmholtz-Zentrum Dresden-Rossendorf (HZDR), wies nach, dass sich eine metallorganische Verbindung als Breitband-Fotodetektor verwenden lässt. Da es keine teuren Rohstoffe enthält, kann es in großen Mengen preisgünstig produziert werden.

Metallorganische Gerüste (Metal-Organic Frameworks, MOFs) haben sich in den vergangenen zwanzig Jahren zu einem gefragten Materialsystem entwickelt. Die hochporösen Stoffe, die
