Raman spectroscopy was conducted on identically exfoliated samples, using a 514 nm wavelength laser under a 50× objective at low power (<5 mW) to avoid sample damage. Three graphene films were identified as single layer graphene by their unique Raman signatures (i.e., Stokes G peak at 1583 cm−1and a single symmetric 2D band around 2700 cm−1; data not shown). AFM measurements of these three films gave heights of 0.8, 1.1, and 1.0 nm.
