Twisted transition metal dichalcogenides（TMDs） homo-bilayers host unique quantum properties,which can be tuned by interlayer twist angle θ.However,the systematic evolution of their typical electronic properties with respect to the twist angle θ,which is crucial for identifying the “special angle” analogous to the “magic angle” of twisted bilayer graphene in correlation physics studies,remains incompletely ***,via scanning tunneling microscopy（STM） and spectroscopy（STS）,we investigate the variation of the moirépotential,flat band,and layer polarization characteristics across a wide range of twist angleθ in twisted bilayer MoS2（TB-MoS2）.The moirépotential of the valence band exhibits a non-monotonic variation with θ,peaking at a maximum value up to 204 me Vat θ～1.7°.Concurrently,at the same θ,the bandwidth of the flat band at the ΓVpoint of the valence band attains its minimum,precisely signifying the “special angle” θc～1.7°in ***,layer polarization in the moirésuperlattice is spatially visualized through the distribution of local density of states（LDOS） at the energies of both ΓVand KVpoints of the valence band,where the polarization degree at the ΓVpoint demonstrates a close dependency on θ.Our findings deepen understanding of twist-angle effect in TMDs,advancing both fundamental physics and practical application.
