<p>A method and structure in which an adsorbate atom or molecule is repositioned on a substrate surface by moving the tip of an STM to a position adjacent to the atom to be moved and causing the atom to be attracted to the tip. While the atom remains bound to the surface (or, alternatively, is lifted), the tip is moved laterally to drag (or carry) the atom to a desired position at which it is bound to the surface. The atom may be repositioned in close proximity to an atom of the same or another type on the same or a different substrate to create a desired multi-atom structure or synthesise a molecule, or an atom may be removed to cleave a multi-atom structure, or a change in state of a multi-atom structure may be effected. Atoms may also be repositioned to write indicia on a storage medium by dragging or carrying atoms into the desired information-bearing pattern, for example, by dragging or carrying selected atoms out of a respective one of a plurality of parallel atom rows using the tip of an STM to thereby write indicia at locations denoted by the removed atoms.</p> |
