| Outline of Final Research Achievements |
We have successfully developed a new high temporal-resolution scanning transmission electron microscopy (STEM). The developed scan coils have 200 times smaller inductances than that in the previous generation, and we can acquire 25 frames of atomic-resolution STEM images as per second (512×512 pixels), where the acquisition time is 83 nano seconds per pixel. Utilizing such high temporal- resolution, it becomes possible to directly observe dynamics of point defects within solids or on the surface. The present study could open the way to perform dynamic STEM observations at atomic-scale.
