Raman spectra of misoriented bilayer graphene
Raman spectra of misoriented bilayer graphene
We compare the main feature of the measured Raman-scattering spectra from single layer graphene with a bilayer in which the two layers are arbitrarily misoriented. The profiles of the two-dimensional (2D) bands are very similar in having only one component, contrary to the four found for commensurate Bernal bilayers. These …
