Mixing at the Interface

Caption

A cross-sectional scanning transmission electron micrograph of the interface between the polar lanthanum chromium oxide (LaCrO3) and the nonpolar strontium titanium oxide (SrTiO3). Although the interface appears to be atomically abrupt, detailed spectroscopic measurements show that cation mixing occurs in the interfacial region.
