Analysis of band structure and scattering phenomena in AA-stacked bilayer graphene: (a) Band structure of AA-stacked BLG along \(\Gamma -K-M\), featuring indicated hopping parameters in the left inset. The analytic behavior of intra-valley scattering is illustrated at \(\phi =\pi /6\) for (b) \(\chi _{11}(q)\) and (c) \(\chi _{12}(q)\) at \(E_{F}=0\) and \(E_{F}=E_{D}=\alpha _{1}\). Colored solid and hollow arrows emphasize the critical momentum \(q_{c}\) governing the scattering on the two Fermi circles. Corresponding plots for inter-valley (\(K-K^{\prime }\)) scattering are shown in (d) and (e).
