Professor Kehui Wu graduated from the Department of Physics of Zhejiang University in 1995 and received his Ph.D. from the Institute of Physics of the Chinese Academy of Sciences (IOP, CAS) in 2000. He then pursued postdoctoral and assistant professor positions at the Institute for Materials Research, Tohoku University, Japan. Returning to China in 2004, he joined the Surface Physics Laboratory at the IOP, CAS, as a researcher and group leader. He also served as the Head of the Public Technology Platform at the Songshan Lake Materials Laboratory. In October 2024, he joined Tsientang Institute for Advanced Study as the Director of the Laboratory for Atomic-Scale Physics and Devices. His research career has been dedicated to the study of scanning tunneling microscopy (STM) and the physical properties of quantum materials. His notable achievements include: 1) pioneering research on the molecular beam epitaxy growth and electric field regulation of transport properties of three-dimensional topological insulators; 2) the discovery of silicene and borophene, two significant single-element two-dimensional materials that have become focal points in the field of 2D materials research; and 3) the independent development of leading-edge analytical techniques and systems, including low-temperature STM, low-temperature STM-tip-enhanced Raman spectroscopy, and terahertz STM, achieving internationally recognized performance levels. He has published more than 200 SCI-indexed papers accumulating over 16,700 citations and an h-index of 53 (Google Scholar). His numerous awards include the Chinese Academy of Sciences Outstanding Scientific Achievement Team Award (as an outstanding contributor), the National Science Fund for Distinguished Young Scholars, and the first-place Beijing Science and Technology Award.
