“…Thus, there are five independent parameters in the Hamiltonian (16) of intrinsic bilayer graphene, namely γ 0 , γ 1 , γ 3 , γ 4 and ∆ ′ . The band structure predicted by the tight-binding model has been compared to observations from photoemission [16], Raman [76] and infrared spectroscopy [55,56,[78][79][80][81]. Parameter values determined by fitting to experiments are listed in Table I for bulk graphite [67], for bilayer graphene by Raman [76,77] and infrared [55,56,80] spectroscopy, and for a This parameter was not determined by the given experiment, the value quoted was taken from previous literature.…”
