Flake Electrical Conductivity of Few-Layer Graphene

Figure 1

Geometry of monolayer graphene in 𝑥𝑦 plane. The dashed lines illustrate the Bravais lattice unit cell. Each cell includes 𝑁_𝑎=2 atoms, which are shown by 𝐴 and 𝐵. The primitive vectors are denoted by 𝐚₁ and 𝐚₂ and 𝑎₀ implies the interatomic distance.
