| Outline of Final Research Achievements |
The atomic scale analysis of amorphous materials has been performed using atomic scale aberration corrected STEM-EELS and theoretical calculation. In addition, the mechanism of visualizing the atoms in glass has been investigated using the multi-slice simulation. We have determined the best condition to visualize the atoms in the glass. The method has been applied to amorphous materials, molten-salt, and fluorescence materials, and we have succeeded in visualize the individual atoms, coordination number, and phase separation in the glas..
