a Equal-filling contours from the band bottom to the charge neutrality for both valleys in the Moiré Brillouin zone. The −1/2 filling Fermi surface is traced out by thick lines. b The Fermi pockets around −1/2 filling are modeled as the triangular shaped Fermi surface in the single-band model. The K and K′ pockets are almost nested along three nesting vectors Q1,2,3
