This study explores the relationship between atomic and electronic structures of correlated superlattices synthesized with atomic-scale epitaxy. Specifically, the study focuses on superlattices made of correlated magnetic SrRuO3 and quantum paraelectric SrTiO3 layers, where the distortion of the RuO6 octahedra is controlled by varying the thickness of the SrTiO3 layers. The customization of the atomic structure affects the electronic structures of both the Ti and Ru compounds, as observed through X-ray absorption spectroscopy. Such atomic-scale epitaxy and spectroscopy provide a unique opportunity to control correlated electronic structures, enabling effective control over intriguing functionalities, such as electromagnetic, thermoelectric, and electrocatalytic behaviors.
