Abstract
The infrared (IR) absorption and resonant Raman spectra of the undoped AA-stackingbilayer graphene have been calculated using density-functional theory in the local densityapproximation. It is found that the undoped AA-stacking bilayer graphene exhibits adifferent characteristic jump and peak structure in its IR spectra, and a different G-bandpeak structure in its resonant Raman spectra, compared with those of the AB-stacking one,which are caused by the different interlayer coupling effects, due to different stacking typesin both of them. Based upon the different IR and Raman spectra, a powerful experimentalmethod can be proposed to identify accurately the stacking type and the layer number infuture experiments.
