摘要：

We report the experimental observation of the out -of -plane optical conductivity in bilayer graphene at a wavelength of 633 nm. While the in -plane optical constants vary by a few percent from the single -layer crystal up to the bulk, this physical quantity depends strongly on interlayer interactions, being at least three times larger in bilayer than in monolayer graphene.
