Observation of the polaronic character of excitons in a two-dimensional semiconducting magnet CrI3

Observation of the polaronic character of excitons in a two-dimensional semiconducting magnet CrI3

Exciton dynamics can be strongly affected by lattice vibrations through electron-phonon (e-ph) coupling. Here, the authors show the presence of strong e-ph coupling in bilayer CrI3 and observe a Raman feature with periodic broad modes up to the 8th order, attributed to the polaronic character of exc...
