Graphene is a single atomic layer of carbon atoms, corresponding to a layer in a graphite crystal.
Its many peculiar physical properties have recently attracted much interest. In graphene research.
Raman spectroscopy is used not only as an indispensible characterization tool to measure the number of layers in a sample and to identify single-layer graphene positively, but also as a probe to investigate its mechanical, electrical, and optical properties. In this review, important recent results in Raman spectroscopic studies of graphene are reviewed.
