Tip-enhannced Raman spectroscopy on nanoscale oxide electronics — •Andreas Rüdiger and Serge Röhrig — Institut für Festkörperforschung, Forschungszentrum Jülich, 52425 Jülich

Tip-enhanced Raman spectroscopy bypasses the diffraction limited lateral resolution of conventional microscopy and provides an apertureless optical tool for true nanoscale characterization. Being sensitive to a very small volume and thus to surface conditions we investigate nanoscale oxide electronics under vacuum and ambient conditions and present recent results for hard- and soft-mode phonons.
