Gold Atom Movement

H.W. Zandbergen
Real time movie of the movement of Au atoms on a (100) surface. The black dots are Au atom columns along the viewing direction. The starting configuration is schematically represented in the inset with red spheres as the atoms on the top. The movie starts with a high mobility of the Au atoms in the top of the plane. At a certain moment the few atoms on the surface are injected into the lower Au plane (blue spheres) resulting in a dislocation in only this plane. The dislocation moves, is mostly trapped near the edge and is finally squeezed out along the viewing direction.
