Complex oxides are renowned for their diverse functionalities that are essential to the advancement of electronics, energy, and information technologies. These functionalities include for example, ferroelectricity, piezoelectricity, and pyroelectricity. The extraordinary physical properties of these materials originate from the complex interactions among lattice, orbital, charge, and spin dynamics. In this talk, I will present our most recent research, focusing on how we can manipulate the properties of oxide heterostructures by intentionally altering their symmetry. A significant part of my presentation will be dedicated to exploring the advancements in freestanding oxide membranes. These have emerged as a groundbreaking platform for experimentalists to design materials with novel properties. Mainly made up of transition metal oxides, these membranes are produced as ultrathin, quasi-2D layers and can be reassembled into multilayered structures, allowing for precision in controlling the twist angles between layers. I will also introduce a pioneering method for creating high-quality complex heterostructures integrated with Si, using SrTiO3 membranes as a universal platform. This aspect of our study paves a new way for embedding electronic devices with multifunctional physical properties into silicon-based technology, promising significant advancements in the field.
