Eine neue Röntgenanalyse an DESYs hellen Forschungslichtquellen weist den Weg zu besseren Solarzellen, Supraleitern und Festplatten. Die Arbeit, die in der aktuellen Ausgabe des Fachjournals "Nature Communications" vorgestellt wird, gibt neue Einblicke in die Phänomene an der Grenzfläche zweier Materialien, wo sich völlig neue Eigenschaften ausbilden können. Mit der Untersuchung hat das Team um Prof. Andrivo Rusydi von der National-Universität Singapur und Prof. Michael Rübhausen vom Hamburger Center for Free-Electron Laser Science (CFEL) ein seit langem unverstandenes Rätsel der Festkörperphysik gelöst. Das CFEL ist eine Kooperation von DESY, der Universität Hamburg und der Max-Planck-Gesellschaft.
