Figure 3: Superposition of a perfect decagon tiling on the high angle annular dark-field (HAADF) lattice image of water-quenched Al72Ni20Co8 obtained by the high angle annular dark field method by Saitoh et al. The overlay decagon tiling is shown separately in the following figure. Note the high degree of order in the lattice image and the near-perfect correspondence with the overlaid decagons.
