Abstract
Wrinkles and blisters of graphene on Ir(111) give rise to remarkably high signals in inelastic electron tunneling spectroscopy due to graphene phonons. Spatially resolved spectra unravel the gradual increase of the graphene phonon signatures with progressive delamination of graphene from the metal surface. Spectroscopy of the Ir(111) surface resonance evidences that the graphene-metal hybridization is efficiently reduced in wrinkles and blisters. A high phonon density of states favors the observation of phonons with wave vectors near the $\overline{M}$ point of the surface Brillouin zone.
