Collection description

Interfaces between different materials underpin both new scientific phenomena, such as emergent behaviour at oxide interfaces, and key technologies, such as the transistor. Control of interfaces between materials with the same crystal structures but different chemical compositions is possible in many materials classes, but less progress has been made for oxide materials with different crystal structures. We show that dynamical self-organisation during growth can create a coherent interface between the perovskite and fluorite oxide structures, which are based on different structural motifs, if an appropriate choice of cations is made to enable this restructuring. Integration of calculation with experimental observation reveals that the interface differs from both the bulk components and identifies the chemical bonding requirements to connect distinct oxide structures. This dataset contains XRD, AFM and RHEED data
