Abstract The energetic and electronic structure of bilayered graphene (BLG) with AA stacking arrangement on a SiO2 substrate is investigated in the presence of an electric field F of different intensities by ab initio density functional calculations. The AA−stacked bilayer graphene is stable on the SiO2 substrate in the absence of an electric field. However, as F increases, the AA-stacked bilayer graphenes are gradually shifted with each other and finally transfers into AB-stacked bilayer graphenes. The bandgap is accordingly changed.
