Oxide interfaces are of interest because. Herein, some recently developed strategies in engineering functional oxide interfaces and their emergent properties are reviewed.ĭefect engineering formal polarization interlayer interaction orbital reconstruction oxide interfaces. Research in oxide interfaces artificially created structures involving transition-metal oxide compounds has flourished over the past decade 1, 2. Reviewed here are the emergent phenomena arising at the interface between oxide materials, which have attracted considerable interest based on advances in thin-film deposition techniques. These emergent phenomena not only serve as a platform for investigating strong electronic correlations in low-dimensional systems but also provide potentials for exploring next-generation electronic devices with high functionality. In the interfaces of non-magnetic complex oxides, one of the most intriguing properties is the emergence of magnetism which is sensitive to chemical defects. Different symmetry constraints can be used to design structures exhibiting phenomena not found in the bulk constituents. Artificial interfacial modifications, which include defects, formal polarization, structural symmetry breaking, and interlayer interaction, have led to novel properties in various complex oxide heterostructures. Recent technical advances in the atomic-scale synthesis of oxide heterostructures have provided a fertile new ground for creating novel states at their interfaces. Complex magnetism and magnetic-field-driven electrical polarization of Co 3 TeO 6. Emergent phenomena at heterointerfaces are directly associated with the bonding geometry of adjacent layers. At the interface of TMO heterostructures, electronic reconstructions generally occur via charge transfer and lead to an extraordinary spectrum of emergent phenomena but unattainable in their bulk constituents. Interface engineering in complex oxide superlattices is a growing field. Complex oxide interfaces have mesmerized the scientific community in the last decade due to the possibility of creating tunable novel multifunctionalities, which are possible owing to the strong interaction among charge, spin, orbital, and structural degrees of freedom. Transitionmetal oxide (TMO) heterostructures provide fertile grounds for creating and manipulating intriguing properties and functionalities.
