Extended Data Fig. 1: Non-interacting spectroscopic properties on another region.

a, STM topography showing the moiré superlattice with θ = 1.14°. b, Scanning tunnelling spectra measured on an AA site for slight electron doping (Vg = −10 V, Vset = −200 mV, Iset = 500 pA, Vmod = 0.5 mV). The blue and green arrows mark the step-like features. c, Band structure calculated using the continuum model including the effects of strain and relaxation. MMΛm is a non-high-symmetry direction along which the Dirac points (protected by C2zT symmetry) are located. The black dotted line indicates the Fermi level. The blue (green) dashed line corresponds to the VHS of the first conduction (valence) remote band. d, Corresponding \(\sqrt{{\rm{L}}{\rm{D}}{\rm{O}}{\rm{S}}}\) (offset by −28 meV) on an AA site. The blue and green arrows mark the VHS of the first conduction and valence remote bands.
