Abstract (EN):
We consider the instability of bilayer graphene with respect to a distorted configuration in the same spirit as the model introduced by Su [Phys. Rev. Lett. 42, 1698 (1979)]. By computing the total energy of a distorted bilayer, we conclude that the ground state of the system favors a finite distortion. We explore how the equilibrium configuration changes with carrier density and an applied potential difference between the two layers.
