Figure 6
Reconstructed phases image viewed along the (a) [0−10] and (b) [−1−10] zone axes. (a) The irregular stacking of unit cells along the c axis is marked by + and − signs. Changes in the handedness of Si columns around gaps are marked by red and blue arrows, and the shifted (Δx = −1/4, Δy = +1/4) subunit is marked with black dotted lines and a red arrow. The black-bordered insets (dashed-dotted lines) are simulated images of RUB-5 polymorphs I, II and III in the [0−10] zone axis orientation. (b) Overlaid structure model and simulated image (dashed-dotted-border inset) of RUB-5 in the [−1−10] zone axis orientation. (c) Power spectra calculated from (a). (d) Power spectra calculated from (b).
