WebJul 14, 2016 · It is shown that the birefringence directly results from the optical anisotropy related to the orthogonal alignment of π*and σ*bonds in the graphene layer. Our polarization analysis reveals a strong bonding of graphene on Co with a reduced σ*excitation energy and a strong tilt of 50%of the pzorbitals towards diagonal orientation.
