The Research Group Spectroscopic Mapping of Correlated Electron Materials is focused on mapping the excitations in correlated electron materials with high spatial and spectral resolution with spectroscopic imaging STM. In correlated electron materials, electronic states have both, localized and delocalized character. This dichotomy of electrons makes the difference to conventional materials, but also renders both their theoretical description and experimental detection difficult. The aim of the research group is to enhance our understanding of the excitations close to the Fermi energy and get a picture of the electronic structure. For this, we use a technique called quasiparticle interference imaging. We develop instrumentation optimized for the retrieval of spectroscopic maps at low temperatures and in high magnetic fields.
