Single‐layer graphene (SLG) can be deposited onto Si/SiO 2 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.
