摘要: Based on first-principles total-energy calculations, we investigate the electronic structure of bilayer graphene under a vertical electric field for various stacking arrangements. We find that near Dirac point is robust against an external and, with exception in Bernal arrangement, maintains its original zero field. also nearly free electron state crosses Fermi level about 0.7 V/A all considered arrangements graphene.
