(a) SEM top surface image of OA-18-4. (b) Structure factor S(q) derived from SEM-image FFT for OA-18-4 (blue circles). The continuous black line corresponds to the best fit using a hexagonal model. (c) S(q) of all AAO samples. From bottom to top: OA-4-4, OA-10-4, OA-18-4, OA-22-4 and OA-18-11. The curves have been vertically shifted for clarity. |
