The dominant experimental technique in our research is electron microscopy, which reveals the structure of materials from the micrometer down to the atomic scale. Electron-transparent specimens are studied by (scanning) transmission electron microscopy ((S)TEM). Surface topography and material contrast of bulk samples are investigated by scanning electron microscopy (SEM). Microstructure analysis is combined with analytical techniques (EDXS: energy dispersive X-ray spectroscopy and EELS: electron-energy loss spectroscopy) for chemical analysis techniques, which can be performed with high spatial resolution in the order of a few nanometers. The investigation of the structural properties is often combined with alternative characterization techniques in collaboration with other groups to obtain correlations between the optical, mechanical or electronic properties with structural properties.
