Tóm tắt

The atomic configuration of phases and their interfaces is fundamental to materials design and engineering. Here, we unveil a transition metal oxide interface, whose formation is driven by energetic influences─epitaxial tensile strain versus oxygen octahedra connectivity─that compete in determining the orientation of an orthorhombic perovskite film. We study this phenomenon in layers of LaVO
