Figure 8From: Site-selective substitutional doping with atomic precision on stepped Al (111) surface by single-atom manipulationThe forces acting on Ag (a) and Au (b) dopant atom in every calculation stepThe forces acting on Ag (a) and Au (b) dopant atom in every calculation step. The red curve is the component force in the Z direction. The black curve denotes the component force in the X direction.Back to article page
