    Research on superconductors and topological insulators composed of one or a few atomic layers has been booming for decades, expecting new quantum phenomena beyond those in three-dimensional crystals. This research trend has appeared by merging research fields of graphene, transition metal dichalcogenide, strong spin-orbit coupling materials on one side, and surface/interface physics and epitaxial growth technology on another side. A large part of such research activity is originated from China.  

    In my talk, I would like to show some examples of research in my group, such as superconducting bilayer graphene with metal intercalation, unconventional superconductivity in single-atomic-layers grown on semiconductor surfaces, and controlling of symmetry in topological surface states. Our specialty in experiments is in-situ transport measurement techniques such as four-tip scanning tunneling microscope in ultrahigh vacuum, which enables to unveil the intrinsic charge/spin transport properties of air-sensitive atomic layers.

Highlight of USTC

According to the latest Nature Publishing Index (NPI) Asia-Pacific and The Nature Publishing Index China, University of Science and Technology of China tops in Chinese universities again. The rankings are based on the number of papers that were published in Nature journals during the last 12 months.
