Imaging Nanometer Phase Coexistence at Defects During the Insulator−Metal Phase Transformation in VO2 Thin Films by Resonant Soft X‑ray Holography

We use resonant soft X-ray holography to image the insulator−metal phase transition in vanadium dioxide with element and polarization specificity and nanometer spatial resolution. We observe that nanoscale inhomogeneity in the film results in spatial-dependent transition pathways between the insulat...
