About this Research Topic
Due to their unique chemical and physical properties, oxide quantum functional materials have broad application prospects in information storage, quantum technology, energy catalysis and other fields. With the rapid development of advanced materials synthesis and characterization methods, it has become possible to study and utilize the surface and interface properties of functional oxide materials at the atomic scale. The oxide quantum functional materials could exhibit new functions or quantum states that are fundamentally different from the corresponding bulk by introducing strain, symmetry breaking and dimension control on the atomic scale surface and interface. These emergent phenomena, which defy the predictions of classical theory, are the key to realizing the unique functions of emerging quantum materials. The novel physical and chemical properties of these materials are determined by the crystal structure and electronic structure at the surface and interface. Advanced characterization techniques, especially the rapid development of extremely bright synchrotron radiation light sources, are one of the powerful tools to characterize them. In addition, the development of various in situ experimental methods has brought new opportunities to oxide quantum functional materials and are expected to resolve some bottleneck problems encountered at present.
To a large extent, the novel properties of oxide quantum functional materials come from the coupling between the degrees of freedom such as spin, charge, orbit and lattice. This Research Topic aims to provide a platform for researchers to share their new concepts, new techniques and new results of the interaction between these degrees of freedom in oxide quantum functional materials using advanced characterization techniques, and to provide guidance for future development.
