| Abstract | We show that the electron-phonon coupling in graphene planar nanostructures gives rise to an enrichment of the absorption spectra around the plasmonic resonances that these structures can support. Furthermore, we estimate the influence of coupling to phonons over the lifetime of these plasmons. In this line, we compute some values of the inelastic damping rate due to this electron-phonon coupling for graphene nanoislands. We conclude that the electron-phonon coupling channel is in general weaker that impurity scattering, and that gives rise to plasmon broadening in the meV range for large structures, whereas for small ones it has a fundamental role in the lifetime of molecular plasmons. |
