▎ 摘　　要

The polarization-resolved Raman-scattering response due to E-2g phonons in monolayer graphene has been investigated in magnetic fields up to 29 T. The hybridization of the E-2g phonon is only observed with the fundamental inter-Landau-level excitation (involving the n = 0 Landau level) and in just one of the two configurations of the circularly cross-polarized excitation and scattered light. This polarization anisotropy of the magnetophonon resonance is shown to be inherent to relatively strongly doped graphene samples with carrier concentrations typical for graphene deposited on Si/SiO2 substrates.
