Raman spectroscopy of graphene under ultrafast laser excitation [PDF]

EPJ Web of Conferences, 2019
The out-of-equilibrium Raman response of graphene is addressed by pulsed laser excitation. Phonon spectrum is rationalized by revisiting the electron-phonon picture in the light of a transient broadening of the Dirac cone.
