Shimizu Group

Dept. Applied Physics and Physico-Informatics, Keio University

We are doing Surface Science using Scanning Probe Microscopy

For Prospective Students and Postdocs

We accept graduate students through our International Graduate Program. If you are interested, please send me (tshimizu at appi.keio.ac.jp (replace at with @) your CV, along with a brief description of your proposed project or your academic interests.

We also welcome students under a short-term exchange program. The Graduate School of Science and Technology at Keio University provides a short-term exchange program, which can last from one semester to a full academic year, for students at partner institutions. For more details, please visit university webpage.

Additionally, we host postdoctoral researchers through the JSPS fellowship programs.


About Shimizu Group

Our group focuses on the characterization of surfaces and interfaces of various materials including metals, semiconductors, oxides, organic thin films, and adsorbed molecules. Scanning probe microscopy at the single atomic and molecular scales provides key information for the understanding of catalytic reaction mechanisms and the development of next-generation devices.


Topics


Our specialty

  • Nanoscale structural analysis using atomic force microscopy (AFM) and chemical analysis combined with infrared spectroscopy in ambient condition
  • Investigation of surface structure and electronic states using scanning tunneling microscopy (STM) under ultra-high vacuum
  • Tip-enhanced Raman spectroscopy in ambient condition
  • Rigorous analysis of technologically relevant nanomaterials with STM, AFM, XPS, IR etc.


Members

Currently, there are 8 graduate students and 5 undergraduate students in our group. We collaborate with various groups inside and outside Japan.
