Many-body effects in suspended graphene probed through magneto-phonon resonances

Stéphane Berciaud, Marek Potemski, Clément Faugeras

We make use of micro-magneto Raman scattering spectroscopy to probe magneto-phonon resonances (MPR) in suspended mono- to penta-layer graphene. MPR correspond to avoided crossings…
