Content of research

We perform the front-line material research by using the cutting-edge electron microscopy techniques to realize novel nanostructures and unanticipated properties. We develop low-voltage TEM/STEM which enables the single molecular imaging and single atom spectroscopy, and high-resolution environmental TEM for the in situ observations of interaction of solid surface with gas atmosphere.

Current Research Programs

• 1. Studies of atoms/molecules confined in nano-space (JST-CREST)
  2. Atomic-level analysis of various low-dimensional materials (JST-CREST)
  3. High resolution EELS for infra-red spectroscopy at a nanometer-scale (JST-CREST)
  4. Momentum-resolved EELS in TEM (ERC Synergy project)
  5. Synthesis of novel materials in an electronically stimulated nanogap (JSPS KAKENHI)
  6. Atomic-scale structural analysis of nanodevices under working environment (JSPS KAKENHI)
  7. ETEM study of automotive catalysts (AICE)
