Outline of Final Research Achievements

The combination of Scanning Transmission Electron Microscopy (STEM) and Electron Energy-Loss Spectroscopy (EELS), that enables to obtain both atomic structures and their electron energy states precisely, plays an very important role in understanding structures and functions of materials properly. The aim of this research is to apply this method to damage-sensitive materials by high-speed, high-sensitive, and damage-free analyses. Systematic studies of (1) the development of image and spectrum acquisition technique, (2) the development of atomic labeling methods, (3) effect of temperature, energy, and other possible environmental factors, and (4) new methods to support materials on ultra-thin substrate or in vacuum for imaging, have been carried out.
