The bilayer grain boundaries (GBs) in chemical-vapor-deposition-grown large-area graphene are identified using multispectral tip-enhanced Raman imaging with 18 nm spatial resolution. misorientation angle of the GBs is determined from a quantitative analysis phonon-scattering properties associated modified electronic structure.
