“…The polaron effects can also influence the transport of excitons, their diffusion, the phononrelated drag, and Raman scattering since the exciton is surrounded by a phonon cloud. These effects are now actively studied in TMDC-based and other layered nanosystems [52][53][54][55][56] .…”

A novel type of exciton-phonon bound state -interlayer polaron -in a double-layer twodimensional semiconductor with transition metal dichalcogenides as an example, is predicted. In these systems the interaction of the interlayer exciton with the soft modes of out-of-plane lattice vibrations caused by van der Waals forces and flexural rigidity gives rise to a bound quasiparticle. The energy and effective mass of the formed polaron for weak and strong exciton-phonon coupling regimes are calculated and analyzed. Possible manifestations of these effects in transport-and spectroscopy-related experiments are discussed.
