Abstract
AbstractWe have developed a phase transmission electron microscopy system that enables real‐time observation of spherical aberration‐free phase images based on active defocus modulation. With the use of this system, the cooperative movement of atoms on an Au(011) reconstructed surface was clearly observed at an atomic level. Relaxation of stress in a deformed crystal was also observed when slipping of (111) atom planes occurred. The dynamic behaviour of an atom‐sized Au wire that was elongated in the [001] direction was observed at a time resolution of 1/30 s, and its behaviour was different from that of a wire elongated in the [011] direction, which was observed in a previous study.
