Tübinger Nahfeldmikroskop liefert höchstaufgelöste optische Bilder eines organischen Halbleiters

Millionenfache Verstärkung des Leuchtens an molekularen Stufen erreicht

(PresseBox) (Tübingen, )
Die Arbeitsgruppe um Prof. Dr. Alfred Meixner und Dr. Dai Zhang vom Institut für Physikalische und Theoretische Chemie der Universität Tübingen hat ein Nahfeldmikroskop entwickelt, das die optischen Eigenschaften einer organischen Halbleiterprobe mit einer Auflösung und Empfindlichkeit zeigt, die lange Zeit aufgrund physikalischer Gesetze als unmöglich galten. Das neu entwickelte Tübinger Mikroskop gestattet es, auf den Nanometer genau gleichzeitig optische Spektren und das Höhenprofil einer Oberfläche zu vermessen - ein Nanometer entspricht einem Millionstel Millimeter. "Molekulare Stufen eines Halbleiterfilms leuchten und sind deutlich als helle 17 Nanometer breite Streifen zu erkennen. Daraus ergeben sich erstaunliche neue Erkenntnisse, die bisher mit pljeai bjadlrj Injxaer qkrxivdh vcmlnd kgymjn", oxwc Jjjwym Ovgaczb. Rkv Quyrywjwkb ocluel fkjas, xww 4.
