Abstract

In article 1905815, Lingfei Wang, Tae Won Noh, and co-workers simply utilize water-leaching to realize an atomic-scale structural modulation at the surface of SrRuO3 epitaxial film: the surface termination converts from SrO to RuO2. The resultant changes in crystal-field symmetry and orbital occupancy stabilize a one-unit-cell-thin insulating surface state in this prototypical metallic oxide.
