a The electronic band structures and the total density of states of pristine gh-C3N4. b The charge distributions of the edge bands C 1 and V 1 (indexed in a). c The orbital-resolved electron density of states projected onto C1 atom, C2 atom, N2 atom, and N3 atom (indexed in b). The energy at the Fermi level is set to zero
