Figure 5
A single layer of Cu atoms (seen in the ab plane) of the (a) Cu2 sublayer, (c) Cu1a sublayer and (d) Cu1b sublayer. Red-tinted atoms mark the occupied sites while the rest are unoccupied. The dashed areas mark the ordered unit cell (supercell) while the fully drawn areas mark the average unit cell. The numbers on the atoms correspond to the location of the atom relative to the origin `O' in the (b) 3D-ΔPDF. The intensity is on an arbitrary scale.
