Figure 6: Structural tiling of (3/2, 2/1)3 approximant.
From: Multiple quasicrystal approximants with the same lattice parameters in Al-Cr-Fe-Si alloys
(a) Atomic resolution HAADF-STEM image along the pseudo-tenfold axis of the (3/2, 2/1)3 approximant. (from Sample 1) (b) Covered with structural tiles. Note that the (3/2, 2/1)3 approximant, depicted in sapphire, consists of SLT-4 tiles, with one tile outlined in red in the upper-right. One enlarged (3/2, 2/1)3 unit cell is inserted in the bottom-right corner.
