Band structure: Noninteracting band structure for pentalayer graphene at a displacement field energy of -40 meV. There is a wide gap between valence and conduction bands, and a zoomed-in view at right illustrates the "flatness" of the active conduction band (red line). This band carries a Chern number of 1.
