Abstract

We present ellipsometric spectra of a graphene flake placed on a surface of oxidized silicon wafer. Our measurements demonstrate that spectroscopic ellipsometry can be successfully used to count the number of graphene layers in a flake. We also show that visible transparency of any two-dimensional system with a symmetric electronic spectrum is governed by the fine structure constant and derive an expression for the absorption coefficient of such a system. © 2011 Springer Science+Business Media B.V.
