Figure 4
(a) Typical moiré pattern of a homophase bilayer made of an oblique structure p2 [ρ = 1.365, φ = 108°, δ = 4°, τ = (0.2, 0.3)Λ] with one atom per unit cell located on the twofold axis; the two lattices
L1 and
L2 are drawn in, respectively, blue and red. (b) The yellow lattice corresponds to the half period of the distribution of the moiré cells whereas in (c) the lattice in cyan of half period gives the internal structure of each cell. |
