Abstract

Direct evidence of the electronic configurations across domain walls in BiFeO₃ is quantitatively characterized by cross-sectional scanning tunneling microscopy. Atomic-scale band evolution and the asymmetrically built-in potential barrier at domain boundaries are demonstrated. The 109° domain walls register a remarkable decrease in the bandgap, suggesting a new route to control the local conducting channels within 2 nm.
