We describe a peculiar fine structure acquired by the in-plane optical phonon at the point in graphene when it is brought into resonance with one of the inter-Landau-level transitions in this material. The effect is most pronounced when this lattice mode (associated with the G band in graphene Raman spectrum) is in resonance with inter-Landau-level transitions 0+, 1 and -,10, at a magnetic field B030 T. It can be used to measure the strength of the electron-phonon coupling directly, and its filling-factor dependence can be used experimentally to detect circularly polarized lattice vibrations.

| Additional Information: | We predicted a peculiar fine structure acquired by the in-plane optical phonon in monolayer graphene (G band in its Raman spectrum) when it is brought into resonance with the lowest inter-Landau-level transition in this material. This effect can be used for a direct measurement of the electron-phonon coupling strength. RAE_import_type : Journal article RAE_uoa_type : Physics |
