Series of 1 × 3 × 2 approximants of the incommensurately modulated BTG structure in projection along [001]: (a) t = 0.01, (b) t = 0.05, (c) t = 0.1, (d) t = 0.15, (e) t = 0.2. For t = 0.25 to t = 0.45, the series is reiterated in the opposite order [from a to e and the whole series (t = 0.0 to t = 0.45), i.e. a to e to a] is repeated once again between t = 0.5 and t = 0.95. A much clearer presentation is given in the supplementary material. |
