## Description

- description: The temperature evolution of the resonant Raman scattering from high-quality
    bilayer 2H-MoS2 encapsulated in hexagonal BN flakes is presented. The observed
    resonant Raman scattering spec- trum as initiated by the laser energy of 1.96
    eV, close to the A excitonic resonance, shows rich and distinct vibrational features
    that are otherwise not observed in non-resonant scattering. The appear- ance of
    1st and 2nd order phonon modes is unambiguously observed in a broad range of temperatures
    from 5 K to 320 K. The spectrum includes the Raman-active modes, i.e. E21g(Γ)
    and A1g(Γ) along with their Davydov-split counterparts, i.e. E1u(Γ) and B1u(Γ).
    The temperature evolution of the Raman scattering spectrum brings forward key
    observations, as the integrated intensity profiles of different phonon modes show
    diverse trends. The Raman-active A1g(Γ) mode, which dominates the Raman scattering
    spectrum at T=5 K quenches with increasing temperature. Surprisingly, at room
    temperature the B1u(Γ) mode, which is infrared-active in the bilayer, is substantially
    stronger than its nominally Raman-active A1g(Γ) counterpart.
