## Description

- description: Two-dimensional layered materials offer the possibility to create artificial
    vertically stacked structures possessing an additional degree of freedom – the
    interlayer twist. We present a comprehensive optical study of artificially stacked
    bilayers (BLs) MoS2 encapsulated in hexagonal BN with interlayer twist angle ranging
    from 0 to 60 degrees using Raman scattering and photoluminescence spectroscopies.
    It is found that the strength of the interlayer coupling in the studied BLs can
    be estimated using the energy dependence of indirect emission versus the A1g-E12g
    energy separation. Due to the hybridization of electronic states in the valence
    band, the emission line related to the interlayer exciton is apparent in both
    the natural (2H) and artificial (62º) MoS2 BLs, while it is absent in the structures
    with other twist angles. The interlayer coupling energy is estimated to be of
    about 50 meV. The effect of temperature on energies and intensities of the direct
    and indirect emission lines in MoS2 bilayers is also quantified.
