Abstract
Twisted MoTe_{2} hosts intriguing correlated quantum phenomena including the fractional quantum anomalous Hall effect in twisted bilayer (t-BL) MoTe_{2} near 3.7°, which is sensitive to the twist angle and moiré superlattices. Here, we directly visualize the twist-angle-modulated electronic structure of t-BL and twisted double-bilayer (t-DBL) MoTe_{2} near this critical angle. We find that the moiré superlattice not only modifies the relative energy between the Γ and K valleys in t-BL MoTe_{2}, but also strongly reconstructs the Γ valley for both t-BL and t-DBL MoTe_{2}. Specifically, the deep p_{z}-derived band at Γ exhibits a distinct splitting that systematically varies with increasing twist angle. Theoretical analysis suggests that this modulation arises from the twist-angle-dependent lattice relaxation, especially interfacial corrugations. Our work directly visualizes the moiré-modulated electronic structure and provides key spectroscopic information of lattice relaxation and interlayer interactions underlying the physics of twisted MoTe_{2}.
