(a) Rectangular-shaped array with a hexagonal lattice (scale bar 50 µm). (b) Elliptical-shaped array with a hexagonal lattice (scale bar 50 µm). (c) SEM showing an array of tilted rectangles (scale bar 10 µm). (d) Quasicrystal pattern (scale bar 10 µm). In (a)–(d) the corresponding diffraction patterns are shown below. The insets in (a) and (b) show high-resolution photographs of the individual Bragg peaks. |
