Direct Observation and Engineering of Oxygen Coordination Environments in Oxide Heterostructures. (English)

Oxygen coordination environments in transition metal oxides often underpin a variety of structural and physical properties. Engineering the oxygen environments in oxide heterostructures is therefore a key for exploring novel phenomena but also for developing novel oxide-based electronic devices. In this article, we present, by ABF-STEM, direct observations of the oxygen coordination environments in heterostructures consisting of perovskite oxides SrRuO3 and GdScO3. We also show that the oxygen coordination environments and magneto-transport properties of the entire SrRuO3 layer can be engineered through the heterointerface structures. The results demonstrate that the oxygen coordination environments can be used as a parameter controlling additional degrees of freedom in functional oxide heterostructures. [ABSTRACT FROM AUTHOR]
