Three-dimensional electron diffraction

Three-dimensional electron diffraction (3DED) is a powerful technique for structural analysis of crystals in nano-scale. Using transmission electron microscopes, it breaks the ground that single crystal structure determination can only be accessible for large crystals (> 5 μm) by X-ray techniques. We are applying 3DED in structural elucidation of nanoporous materials, and advance our knowledge on structure-property relationships. We are also actively developing new 3DED techniques to reveal more details of functional materials.

High resolution imaging methods

High resolution transmission electron microscopy (HRTEM) imaging can provide detailed information about atomic arrangements in real space. By using aberration-corrected TEM, we are investigating the atomic structures of nanoporous materials in a sub-nanometer resolution, particularly for their local structures and defects.
