Abstract
We report a mechanism of lateral manipulation of single Fe adatoms on the surface of the topological insulator Bi2Se3 with atomic force microscopy. The Fe atoms are embedded within the sparsely packed surface layer, rendering them inaccessible to classical manipulation methods. Nevertheless, we find a manipulation mechanism in which the Fe atom is plucked from its adsorption site and can be ...
We report a mechanism of lateral manipulation of single Fe adatoms on the surface of the topological insulator Bi2Se3 with atomic force microscopy. The Fe atoms are embedded within the sparsely packed surface layer, rendering them inaccessible to classical manipulation methods. Nevertheless, we find a manipulation mechanism in which the Fe atom is plucked from its adsorption site and can be pulled along the surface. We demonstrate the controllability of this pluck-pull manipulation by the construction of a small nanostructure.
