Figure 3
(a) 7800 vertex positions of the OQC in Ba–Ti–O/Pt(111) represented in physical space. The coloring of the vertices represents their internal space distance from the origin of the AD, as shown in Fig. 1[link](a). The red circle encloses 1800 vertices for which the internal space variance is presented in Fig. 4[link]. (b) Enlarged view of the area inside the red rectangle in (a). Some characteristic dodecagons are marked as a guide to the eye.
