Overview of Research Group, Goals and Purposes:

Disordered materials indicates, in a broad sense, all the non-crystalline materials: the materials which do not have long-range periodicity such as glass or liquids, and functional materials that has heterogeneity in the structure. To study these disordered materials, it requires different techniques and structural analysis from those for crystalline materials. There is a need to promote the enhancement and development of the corresponding experimental / analytical methods or sample environments special for them.

This study group, as a platform of disordered materials research at SPring-8 / SACLA, promotes the activation of a wide range of research from fundamental to the application, and make recommendations to the facility. In addition, it also plays a role of first-contacting person for new users who target disordered materials.

Relevant experimental techniques are x-ray diffraction, anomalous x-ray scattering (AXS), x-ray absorption fine structure (XAFS), small-angle x-ray scattering (SAXS) for the static structures, and inelastic x-ray scattering (IXS) for the dynamics. RMC (Reverse Monte Carlo) simulation technique is also important to analyze and visualize the structure of the materials.
