Fig. 4: Flat band in VBM of MoS2.

a–c Micro-ARPES from pristine monolayer MoS2 (left) and MoS2-bP superlattices with θ = 8.5° (middle) and θ = 2.4° (right) along the Γ–K direction closest to AC direction. d–f The corresponding second derivatives of panels a–c. The dashed lines represent the highest energy levels at the Γ and K points. g EDCs of pristine monolayer MoS2 and MoS2-bP superlattices taken at momentum positions of Γ and K points. The VBM is indicated by the dashed line.
