DFT-simulated electrostatic potentials, Δρ, of the benzene/Br/Ag(111) superlattice (a), the M-C66/Br/Ag(111) superlattice (c), and the C66/Br/Au(111) superlattice (e), respectively, superimposed with the structural model at bottom of each panel. The k-space dispersion of the electronic bands of the kagome lattice (b), the breathing kagome lattice (d), and the chiral breathing diatomic-kagome lattice (f), respectively, calculated using the TB model with different tilting angles and hopping constants t1 = t2 = 0.175 eV (b), t1 = 0.175 eV, t2 = 0.20 eV (d), and t1 = t2 = 0.50 eV, t3 = 0.60 eV (f). The flat bands (FBs) are highlighted with red.
