Query: Lateral manipulation with combined atomic force and scanning tunneling
  microscopy using CO-terminated tips   CO-terminated tips currently provide the best spatial resolution obtainable
in atomic force microscopy. Due to their chemical inertness, they allow to
probe interactions dominated by Pauli repulsion. The small size and inertness
of the oxygen front atom yields unprecedented resolution of organic molecules,
metal clusters and surfaces. We study the capability of CO-terminated tips to
laterally manipulate single iron adatoms on the Cu(111) surface with combined
atomic force and scanning tunneling microscopy at 7\,K. Furthermore, we find
that even a slight asymmetry of the tip results in a distortion of the lateral
force field. In addition, the influence of the tilt of the CO tip on the
lateral force field is inverted compared to the use of a monoatomic metal tip
which we can attribute to the inverted dipole moment of a CO tip with respect
to a metal tip. Moreover, we demonstrate atom-by-atom assembly of iron clusters
with CO tips while using the high-resolution capability of the CO tips in
between to determine the arrangement of the individual iron atoms within the
cluster. Additionally, we were able to laterally manipulate single copper and
silicon adatoms without changing or losing the CO from the tip's apex.
