## Description

- description: The moir ́e superlattice has emerged as a powerful way to tune excitonic
    properties in two-dimensional van der Waals structures. However, the current understanding
    of the influence of the twist angle for interlayer excitons in heterostructures
    is mainly limited to momentum-direct K − K transitions. In this work we use a
    judicious combination of spectroscopy and many-particle theory to investigate
    the influence of the twist angle on momentum-indirect interlayer excitons of a
    MoSe2/MoS2 heterostructure. Here, the energetically lowest state is a dark and
    strongly hybridized ΓK exciton. We show that increasing the twist angle from an
    aligned structure (0◦ or 60◦) gives rise to a large blue shift of the interlayer
    exciton, which is a manifestation of the strong dehybridization of this state.
    Moreover, for small twist angle samples, our photoluminescence measurements reveal
    contributions from two interlayer exciton states, which our modellingattributestothetransitionsfromdifferentmoir
    ́e-minibands. Our finding contributes to a better fundamental understanding of
    the influence of the moir ́e pattern on the hybridization of dark interlayer exciton
    states, which may be important for applications in moir ́etronics including novel
    quantum technologies.
