Welcome to the Atomic-Scale Microscopy & Spectroscopy Group!

This group utilizes low-temperature scanning probe microscopy (SPM) that visualizes individual atoms and molecules in real space. We also perform localized spectroscopic measurements by irradiating the SPM junctions with laser light. This provides information on the sub-nanometer scale beyond the simple topography. The goal of this group is to understand the origin of characteristic chemical/physical phenomena at solid material surfaces and molecules adsorbed on the surfaces at the atomic level by high spatial resolution imaging and spectroscopy techniques.


    A poster prize winner here!
    May 2024

    Max Halbauer won a poster prize at a seminar he attended (809. WE-Heraeus-Seminar, Bad Honnef). This is his first academic award, but I am confident that this is just the beginning of his many accomplishments! Congratulations, Max!
    Joint workshop with ISSP, Japan
    Mar 2024
    We organized a two-day workshop on “THz and SFG spectroscopy and related phenomena in Solid-State Physics and Surface Science.” We invited one full professor, four research assosiates, and four PhD students from the Institute for Solid State Physics (ISSP, the University of Tokyo, Kashiwa, Japan) and Kyoto University (Kyoto, Japan) for a strong scientific exchange through the workshop and lab tours. We hope that their visit triggers further scientifc development of each other’s institutions!
    Two research stays
    Nov 2023
    Two PhD students, Aji from Charles University and Kyungmin from Osaka University, are staying our group to experiment on their individual samples.
    We hope that both make good progress with us!
    A Journey into Surface Science and Molecular Chemistry
    Sep 2023
    Some of my group members visited the Institute of Molecular Science (IMS) and prominent universities in Japan for in-depth discussions with leading groups in surface science, atomic force microscopy, and organic chemistry. At three universities, Max gave individual seminars to four labs. (The photo shows one of them, Nozaki Lab at the University of Tokyo.)
    Presented at the Department Workshop
    Jun 2022
    We finally had the opportunity to meet face-to-face with colleagues in our department and discuss our recent research in depth. We enjoyed the workshop at a wonderful venue on lake Griebnitzsee, Berlin/Potsdam.
