Figure 8
The eigenmodes shapes at the edges of the BG. Panels (a–d) correspond to the eigenmodes shapes at the point Γ of the sixth band when λ = 0, 0.01, 0.02 and 0.03, respectively. Panels (e–h) correspond to the eigenmodes shapes at the point Γ of the thirteenth band when λ = 0, 0.01, 0.02 and 0.03, respectively.
