Direct experimental access to its momentum-resolved electronic structure is essential for uncovering the microscopic origins of these correlated topological phases. Here, we report angle-resolved photoemission spectroscopy measurements of twisted bilayer MoTe2, revealing pronounced twist-angle-dependent band reconstruction shaped by orbital character, interlayer coupling and moiré potential modulation. Density functional theory captures the qualitative evolution, yet underestimates key energy scales at larger twist angles, highlighting the importance of electronic correlations. Notably, the hole effective mass at the K valley exhibits a non-monotonic dependence on twist angle, peaking near 2°, consistent with band flattening at the magic angle predicted by continuum models. By benchmarking them against experimental input, we refine the theoretical description of twisted bilayer MoTe2. Finally, we demonstrate tunable electronic structure via electrostatic gating and surface dosing, enabling direct observation of the conduction band minimum to confirm a direct band gap in tMoTe2. These results establish a spectroscopic foundation for modeling and engineering emergent quantum phases in this moiré platform. description_type: abstract lang: und ## Creator - name: Yujun Deng role: author - name: William Holtzmann role: author - name: Ziyan Zhu role: author - name: Timothy Zaklama role: author - name: Paulina Majchrzak role: author - name: Takashi Taniguchi role: author orcid: https://orcid.org/0000-0002-1467-3105 organization: National Institute for Materials Science - name: Kenji Watanabe role: author orcid: https://orcid.org/0000-0003-3701-8119 organization: National Institute for Materials Science - name: Makoto Hashimoto role: author - name: Donghui Lu role: author - name: Chris Jozwiak role: author - name: Aaron Bostwick role: author - name: Eli Rotenberg role: author - name: Liang Fu role: author - name: Thomas P.
