Professor Ruijuan Xu joined the Materials Science and Engineering faculty at NC State in July 2022. She received her Bachelor of Engineering (B.E.) degree from Zhejiang University, her M.S. from the University of Illinois at Urbana-Champaign, and her Ph.D. from the University of California, Berkeley, all in the field of Materials Science and Engineering. Before starting at NC State in 2022, Xu received the prestigious Stanford Geballe Laboratory for Advanced Materials (GLAM) postdoctoral fellowship to perform her postdoctoral research in the department of Applied Physics at Stanford University, where she focused on studying emergent ferroelectricity in freestanding complex oxide membranes. The research of the Xu Group focuses on developing low-dimension materials (thin films, heterostructures, nanomembranes, and nanostructures) that display novel ferroic (ferroelectric, ferromagnetic, multiferroic), nanomechanical, and electromechanical properties, and utilizing various external stimuli to achieve the control of the emerging properties in these materials for next-generation nanoelectronics. A primary focus in her group is using a combination of atomic-scale synthesis such as pulsed-laser deposition, nanoscale manipulation, device fabrication, and a variety of structural and electrical characterization methods to understand the structure-property relationship in these materials on the nanoscale.
