Fig. 2: AFM image of MoMo molecules on calcite (10.4) as a function of coverage.
From: Creating a regular array of metal-complexing molecules on an insulator surface at room temperature
a At a low coverage of 0.07 molecules per nm2, single molecules are obtained. b Upon increasing the coverage to 0.41 molecules per nm2, areas with higher molecule density are seen, however no ordered inner structure is visible. c At a high coverage of 0.65 molecules per nm2, partly ordered domains can be observed. d Some ordered domains are marked with a white circle. Height profiles along the \(\left[ {42\bar 1} \right]\) (yellow arrow) and \(\left[ {0\bar 10} \right]\) (blue arrow) direction are displayed. The white calcium ions indicate the substrate lattice. MoMo adsorbs exclusively on identical adsorption sites.
