12. Submolecular resolution is defined as the ability to resolve atomic positions within molecules. Here, we refer to subatomic resolution as the ability to image single atoms as nontrivial features such as tori or multiple extrema, in contrast to single protrusions or single depressions.

Our initial experiments of evaporating Fe atoms on Cu(111) appeared to confirm the findings of the inverse of the threefold tip 3 of (8), because we found many threefold structures that we first misinterpreted as single atoms. It turned out that upon extended Fe evaporation, the copper crystal heated up to ∼15 K and the Fe monomers became mobile enough to form an abundance of trimers.
