Figure 6: Transmission electron microscopy.
From: Anisotropic two-dimensional electron gas at the LaAlO3/SrTiO3 (110) interface
High-angle annular dark-field STEM images of the LaAlO3 film on the SrTiO3 (110) substrate shows an epitaxial growth of the LaAlO3/SrTiO3 (110) heterostructure (A-site atoms La and Sr are indicated by red and blue, respectively, and the B-site atoms Al and Ti by orange and purple, respectively). A magnified view of the elemental mapping across the interface is also shown on the right side. Scale bar, 2 nm.
