Figure 1.

Illustration of three different MSLs formed in a hBN/graphene/hBN heterostructure. Blue, black, and red hexagonal lattices represent top hBN, graphene, and bottom hBN lattices, respectively. ϕ₁ (ϕ₂) is the twist angle between top (bottom) hBN and graphene. θ₁ (θ₂) indicates the orientation of the corresponding MSL with respect to graphene. The resulting moiré periods are indicated with λ_1,2,3. The 3L-MSL (middle part) has a larger period than both 2L-MSLs (left and right parts). Insets: moiré potential calculations.
