摘要:

As modern technologies are dominated by interface-derived materials, such as semiconductor heterojunctions, oxide heterostructures are an emerging frontier in hunting for the next generation of functional materials. Complex oxides are a class of quantum materials where the electrons strongly interact with each others and self-organize into a diverse variety of intriguing competing phases, such as superconductivity, magnetism, and multiferroics. Interfacing oxides with distinct ground states provides a fascinating platform at nanoscale for controlling, designing and artificially creating innovative correlated systems that are unobtainable by conventional solid state chemistry. The interplay among the entangled charge, spin, and orbital degrees of freedom at interfaces also affords a unique approach for comprehending the underlying correlated physics. In this talk I will discuss utilization of epitaxial interfaces for driving metal-insulator transition, orbital polarization, spin dynamics, magnetic anisotropy and topological semimetallicity. I will summarize our investigations on several model systems involving 3d and 5d correlated electrons. Experimental results from atomic layering growth of heterostructures to advanced synchrotron-based characterizations will be discussed to illustrate findings that facilitate quantum materials by design.
