Extended Data Fig. 4: Domain boundary contrast images obtained from TTG.
From: Unconventional domain tessellations in moiré-of-moiré lattices
a–f, SAED (panels (i)) and DF TEM images (panels (ii)–(iv)) using the three sets of second-order Bragg peaks obtained from TTG with various twist-angle combinations. Each of the Bragg peaks used to obtain DF TEM images shown in panels (ii)–(iv) are marked with red, green and blue arrows in the SAED images. SAED and DF TEM images are obtained for the experimentally observed phases shown in the main text (Fig. 3): simple triangular domain lattice (a), simple triangular domain lattice bound by moiré-of-moiré boundaries (b), double-coloured triangular domain lattice (c), kagome-like domain lattice (d), coloured triangular domain lattice (e) and hexagram domain lattice (f).
