Figure 6From: Site-selective substitutional doping with atomic precision on stepped Al (111) surface by single-atom manipulationThe process of positioning Au dopant to the Al step site by Au single-apex tip. (a) Lower down the tip upon the site. (b) Move the tip laterally in the X direction. (c) The Au tip is deformed while moving laterally. (d) The dopant atom is released successfully.Back to article page
