      abstract     = {Structural transformations in strongly correlated materials
                      promise efficient and fast control of materials’
                      properties via electrical or optical stimulation. The
                      desired functionality of devices operating based on phase
                      transitions, however, will also be influenced by nanoscale
                      heterogeneity. Experimentally characterizing the
                      relationship between microstructure and phase switching
                      remains challenging, as nanometer resolution and high
                      sensitivity to subtle structural modifications are required.
                      Here, we demonstrate nanoimaging of a current-induced phase
                      transformation in the charge-density wave (CDW) material
                      1T-TaS$_2$. Combining electrical characterizations with
                      tailored contrast enhancement, we correlate macroscopic
                      resistance changes with the nanoscale nucleation and growth
                      of CDW phase domains. In particular, we locally determine
                      the transformation barrier in the presence of dislocations
                      and strain, underlining their non-negligible impact on
                      future functional devices. Thereby, our results demonstrate
                      the merit of tailored contrast enhancement and beam shaping
                      for advanced operando microscopy of quantum materials and
                      devices.},
