Sangjae Lee

Sangjae Lee is a Postdoctoral Associate at Seoul National University, focusing on condensed matter physics. His research explores the electronic structure and collective excitations in transition metal compounds, utilizing advanced techniques like molecular beam epitaxy (MBE) and synchrotron x-ray characterization. His work aims to manipulate material properties through dimensional confinement and interfacial engineering.

Research Interests: Lee’s research centers on understanding the interplay of structural and electronic degrees of freedom in transition metals. Key areas include studying novel phenomena such as superconductivity and magnetism in confined systems, and how these can be controlled via thin film heterostructures. His studies involve manipulating charge, orbital, and spin configurations to uncover exotic phases and emergent properties.

His recent work encompasses three main studies: modifying LaCoO3’s electronic structure through bi-layer heterostructures, investigating spin excitations in Fe thin films, and adjusting exchange interactions in NdNiO3 heterostructures. These studies integrate high-quality thin film synthesis with theoretical models and advanced characterization.
