Research Activities

Novel physics and chemistry, developed by operando measurement and material synthesis

We are developing techniques of advanced soft X-ray spectroscopy using high-brilliant synchrotron radiation, X-ray free electron laser, and high-order harmonic laser. Our main research is materials science at atomic layers and surfaces/interfaces. We precisely evaluate electronic states by high-resolution measurements, explore functionalities by operando observations, develop new experimental methods, and synthesize exotic 2D materials. By comprehensively developing these studies, we are constructing novel physics and chemistry in matters, based on symmetry, dimensionality, and topology, for example.

We are organizing a beamline end-station for X-ray absorption spectroscopy (NEXAFS) and X-ray photoelectron spectroscopy (XPS) measurements with nano-to-micrometer spatial resolution. Elements or chemical states (electronic states) of matters can be analyzed quantitatively with high precision. Chemical reactions can also be tracked at the solid-gas interface in real time (the operando condition). The beamline is useful for functional analyses of catalysts and energy materials as well as for evaluation of physical properties of advanced materials. Currently, we are launching an additional system that can examine the synthesis process with informatics and robot technology. In the future, we plan to realize a new use of synchrotron radiation that transcends the boundaries between "analysis" and "synthesis"
