Research contents

Various materials properties used in many industrial fields can be caused by fine fluctuations of structural arrangements, compositions, and chemical bonding states in atomic scale. It is important to measure such local fluctuations in materials accurately and precisely, which requires both atomic-level spatial resolution and single-atom sensitivity in characterization. In this research division, we conduct materials fine-structure characterization by transmission electron microscopy (TEM) and scanning electron microscopy (SEM) in combination with and chemical composition/sate analysis through X-ray energy dispersive spectrometry (XEDS) and electron energy-loss spectrometry (EELS).
