Interlayer Exciton-Phonon Coupling in MoSe₂/WSe₂ Heterostructures.

ABSTRACT: Transition metal dichalcogenide heterostructures have garnered strong interest for their robust excitonic properties, mixed light-matter states such as exciton-polaritons, and tailored properties, vital for advanced device engineering. Two-dimensional heterostructures inherit their physics from monolayers with the addition of interlayer processes that have been particularly emphasized for their electronic and optical properties. Here, we demonstrate the interlayer coupling of the MoSe₂ phonons to WSe₂ excitons in a WSe₂/MoSe₂ heterostructure using resonant Raman scattering. The WSe₂ monolayer induces an interlayer resonance in the Raman cross-section of the MoSe₂ A_1g phonons. Frozen-phonon calculations within dens
