From: Polarized Raman spectroscopy with differing angles of laser incidence on single-layer graphene
Polarized Raman spectra of a bulk graphite in the backscattering geometry. (a) Polarized Raman spectra of a bulk graphite in the backscattering geometry with differing angles (θ) of the laser incidence. (b) Normalized Raman intensity of the 2D-band in out-of-plane configuration with respect to that in in-plane configuration as a function of laser incidence angle. The black line represents cos2 θ.
