Quantum Beam Diffraction Group

The first step in understanding why a material expresses a function is to study its atomic arrangement. We will develop experimental and analytical techniques using various quantum beams, centered on diffraction experiments using high-brilliance synchrotron radiation X-rays. We will also attempt to realize high-throughput measurement and analysis by introducing measurement informatics and artificial intelligence, and to compile a database of the obtained results. Furthermore, we will attempt to construct an autonomous measurement, prediction, and material synthesis circulation system based on these technologies to accelerate materials research. The target materials range from crystalline materials with a regular arrangement of atoms to amorphous materials and liquids with less regular atomic arrangement.
