                      photoemission microscopy for the analysis of future
                      electronic devices for the information technology is
                      studied. The long-term perspective is the analysis of the
                      switching-dynamics in oxide-based nonvolatile resistive
                      memories. These are regarded as promising new components in
                      the development of more powerful processing units or storage
                      devices, since the improvements of the classical silicon or
                      magnetism-based technologies are approaching their physical
                      limits. Nevertheless, the efficiency and functionality of
                      suitable material systems strongly depend on the quality and
                      properties of their surfaces and interfaces. The
                      energy-filtered photoemission microscopy provides a
                      spatially resolved chemical study of these systems,
                      especially in combination with high brilliance synchrotron
                      light sources. The high photon intensities are needed, if
                      characteristic core levels of a specimen should be analyzed
                      with a high spatial and energy resolution. Studies of
                      metal-insulator-metal structures based on the valence change
                      effect in strontium titanate, which is a model system for
                      resistive switching devices, showed that the spatial
                      resolution needs to be in the 100 nm regime and the
                      energy-resolution in the 100 meV regime to resolve the
                      relevant changes in a switching cycle. Therefore, a big
                      focus of this thesis lies on the determination of the
                      relevant experimental parameters which are needed to fulfill
                      these requirements. Another challenging task is to study the
                      functional layer of such a device through a capping
                      electrode. Hard X-ray synchrotron radiation allows the use
                      of high kinetic energy photoelectrons with an up to ten
                      times lager information depth. In this thesis it is shown
                      for the first time, which spatial resolution can be achieved
                      when detecting chemically different regions through cover
                      layer thicknesses of up to 15 nm. Microscope-relevant topics
                      like transmission and aberration effects are discussed with
                      respect to the use of high kinetic electrons and illustrated
                      by calculations.},
