Dr. Jae-Chun Jeon is a leading experimental physicist specializing in spintronics, unconventional computing devices (e.g., neuromorphic computing, P-bit computing, etc.), and cryogenic devices within the NISE department. His work mainly focuses on unraveling the underlying physics and functionalities of these advanced materials and devices, employing high-speed, sophisticated electrical transport measurements and data analysis techniques. Dr. Jeon earned his Ph.D. in condensed matter physics from the University of Alberta, Edmonton, Canada, in 2016. Following his doctorate, he continued his research as a postdoctoral fellow at the same university, focusing on strongly correlated magnetic oxide materials for spintronic and neuromorphic applications. He joined the NISE department in 2018.

Main research interests

My research focuses on unravelling the physics of complex systems, such as spintronics, correlated oxides, and atomically engineered materials, to discover their advanced functionalities. I am particularly interested in manipulating spin textures and states using spin electrons, including current-induced domain wall motion and spin-orbit torque-induced magnetization switching, for memory and logic applications. A key aspect of my research is the development of racetrack memory, which shows foreseeable potential not only for conventional binary memory but also for unconventional analogue (non-binary) systems, such as probabilistic-bit and neuromorphic devices. Our work is supported by cutting-edge atomically thin film deposition systems, state-of-the-art electronics, and advanced device fabrication techniques, including electron beam lithography and ion beam etching/deposition.
