报告摘要:

Oxides interfaces attract enormous interest because of their great potential for next-generation electronic devices in recent years. The interplay of spin, orbital, charge, and lattice degrees of freedom at interfaces endows these heterostructures to create a variety of novel physics and functionalities, such as interface superconductivity, magneto-electric coupling, and the quantum Hall effect,etc. Among various complex oxides, one perovskite, Strontium Ruthenate (SrRuO3, SRO), is a very fascinating material that exhibits itinerant ferromagnetism, wide absorption spectrum across the visible light, and photostriction. Its superior physical properties also contribute it to be an extremely important platform for integration of other materials into oxide devices. This talk focuses on light-driven functional control through tight structural coupling in oxide heterostructures using the photostrictive effect of SRO. Several interesting systems, including thin films, superlattices, self-assembled nanocomposites, will be introduced. These SRO-based heterostructures reveal that electronic orderings, and even the corresponding physical properties are strongly correlated to light-dependent controllability of structural ordering. These systems open a gate to explore novel optical-coupled functionalities with particular design in interface and strain engineered strongly correlated oxide heterostructures.
