Subsurface Oxygen Vacancy Mediated Surface Reconstruction and Depolarization of Ferroelectric BaTiO3 (001) Surface

Abstract The interplay between surface reconstruction and depolarization of ferroelectric oxide surfaces is strongly influenced by oxygen vacancies (VO). Using in‐situ atomic‐resolution electron microscopy imaging and spectroscopy techniques, it is directly observed that a clean BaTiO3 (001) surface...
