Raman study on the interlayer interactions and the band structure of bilayer graphene synthesized by alcohol chemical vapor deposition - art. no. 151916

[摘要]：We investigated the electronic band structure and interlayer interactions in graphene synthesized by alcohol-chemical vapor deposition (a-CVD) using microprobe Raman spectroscopy and tight-binding band-structure calculations. The number of graphene layers was determined from the spectrally integrated intensity ratios of the G phonon to 2D phonon peaks. We found that the value of the parameter determining interlayer interactions in a-CVD bilayer graphene was less than half that of exfoliated bilayer graphene. The weak interlayer interaction in a-CVD bilayer graphene was attributed to non-AB stacking order. (C) 2011 American Institute of Physics. [doi:10.1063/1.3651325]
