      abstract     = {Materials with insulator-metal transitions promise advanced
                      functionalities for future information technology.
                      Patterning on the microscale is key for miniaturized
                      functional devices, but material properties may vary
                      spatially across microstructures. Characterization of these
                      miniaturized devices requires electronic structure probes
                      with sufficient spatial resolution to understand the
                      influence of structure size and shape on functional
                      properties. The present study demonstrates the use of
                      imaging soft X-ray absorption spectroscopy with a spatial
                      resolution better than 2 μm to study the insulator-metal
                      transition in vanadium dioxide thin-film microstructures.
                      This novel technique reveals that the transition temperature
                      for the conversion from insulating to metallic vanadium
                      dioxide is lowered by 1.2 K ± 0.4 K close to the structure
                      edges compared to the center. Facilitated strain release
                      during the phase transition is discussed as origin of the
                      observed behavior. The experimental approach enables a
                      detailed understanding of how the electronic properties of
                      quantum materials depend on their patterning at the
                      micrometer scale.},
