Fig. 4. Two layer 22.6° twist (a) measured SAED pattern (b) model of supercell viewed down c-axis with second layer rotated 22.6°. The base layer FeS is represented in solid spheres and rotated layer in open circles (c) supercell viewed along a-axis (d) simulated ED from supercell model (e) simulated pattern in 4d superposed on 4a (f) families of lattice planes corresponding to reflections circled in red and blue in 4e.
