Single-layer graphene (SLG) can be deposited onto Si/SiO2 substrates from aqueous dispersions using a scalable and quick detergent-based method that takes advantage of the availability and low cost of graphite as a feedstock, report Andreas Hirsch and co-workers on p. 4265. The deposits were analyzed using absorption and Raman spectroscopy and atomic force and optical microscopy. Evaluation of the two-phonon defect-induced Raman peak of individual particles on the substrate was then used to confirm exfoliation into graphene monolayers.
