Yi Ji

Yi Ji is an Associate Professor in the Department of Physics and Astronomy at the University of Delaware. He joined the faculty in 2006 and serves as the Graduate Program Director (2020–present). His research focuses on spintronics, exploring spin injection, transport, and functionality in mesoscopic metallic heterostructures. Key areas include enhancing spin relaxation lengths, studying spin transfer torque effects, and investigating Kondo spin relaxation. He holds a Ph.D. from Johns Hopkins University (2003) and a B.S. from Peking University (1997).

Research interests emphasize experimental studies using advanced equipment such as thin film deposition systems, electron-beam lithography, and cryogenic magneto-transport setups. His lab, the Mesoscopic Spintronics Lab, collaborates with the University of Delaware Nanofabrication Facilities. Notable contributions include demonstrating copper spin relaxation lengths exceeding 3 micrometers and exploring ionic-gated spin relaxation tuning.

Yi Ji has supervised seven Ph.D. students, many of whom now hold industry and academic positions. His work appears in top journals and is accessible via Google Scholar and ORCiD profiles. He has held postdoctoral roles at Argonne National Laboratory (2003–2006) and maintains active participation in experimental condensed matter physics.
