Description
Oxide heterostructures exhibit various fascinating properties such as ferroelectricity, ferromagnetism, and superconductivity. They simultaneously find widespread applications in clean energy, neuromorphic devices, novel devices based on interface states, and more. Due to their versatile nature, extensive research is underway. In this talk, I will present the latest advances in quasi-two-dimensional oxide quantum materials synthesized through topotactic reduction reactions in thin film heterostructures [1,2]. These materials can enter diverse quantum states, such as Jahn-Teller ordering and unconventional superconductivity, depending on their d-electron filling states. Given the tunability of quantum phenomena, topotactic engineering offers a promising material platform that could contribute to the designing of innovative quantum devices for future computation and information technology.
