Nanoprobe Group

Ultra-high resolution measurement and nanomaterial development using state-of-the-art scanning probe microscopy

Scanning probe microscopes, which can measure surface structures and states in real space and at ultra-high resolution, are important measurement devices that support today's nanoscience. The Nanoprobe Group is developing state-of-the-art atomic force microscopes and scanning tunneling microscopes that can operate in a variety of environments, from extreme environments such as ultrahigh vacuum, cryogenic temperature, and in magnetic fields to room temperature with controlled atmosphere. We are also exploring the basic science of surface chemistry and surface physics using these microscopes, and developing techniques for measuring operando potentials of battery materials and other materials, aiming to contribute to the development of nano, quantum, environmental, and energy materials.

Field of Expertise/Research Subjects

 

• Single-molecule chemistry using ultra-high resolution AFM/STM
• Surface and organic synthesis of carbon nanostructures
• Development of advanced measurement technology related to cryogenic AFM/ STM and its functionalization
• Detection of novel physical phenomena using cryogenic STM in a magnetic field
• Development of in-situ and operando potential measurement by KPFM
