Development of a Microscope Capable of Observing Electron Behavior with 1-Micrometer Resolution ~Expected to Accelerate Research on Quantum Materials and Next-Generation Information Processing Devices~

A research group including Researcher Kohei Yamamoto and Senior Principal Researcher Jun Miyawaki of the National Institutes for Quantum Science and Technology (QST), and Assistant Professor Hiroto Suzuki of the Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, has successfully developed a microscope capable of visualizing the behavior of electrons in materials with a spatial resolution of one micrometer or less.

This achievement was realized using QST’s resonant inelastic X-ray scattering (RIXS) instrument “2D-RIXS”, which has ultra-high energy resolution capable of distinguishing extremely small differences in electronic energy states. The instrument is installed at NanoTerasu.

This is the first time in the world that electron behavior inside materials has been visualized with micrometer-scale spatial resolution using a RIXS instrument. The new technique is expected to accelerate research on quantum materials and the development of next-generation information processing devices.
