Outline of Final Research Achievements

A wave-field restoration transmission electron microscope (TEM) system was newly developed for in-situ dynamic observation. In the new system, the change of focus accompanying the specimen drift was automatically corrected at a video frame rate, while performing simultaneous correction of spherical aberration, two and three fold astigmatism and coma aberration. The precision of the focus tracking was 0.3 nm, which was enough high to discuss the atomic structures in detail.
This technique was applied to study the graphen synthesis by cobalt nano particles, and the matrix crystal lattice of the particle and graphene sheets were separately observed. By analyzing the atomic structures, it became clear that there was a large distortion at near the surface area, where some precursors showing dark line contrast were often observed. The dynamic observation indicates that the graphene sheets are formed not on the topmost surface of the particle, but beneath the surface by a few atomic layers.
