Graphene raman 633nm
WebAt first glance, the Raman spectrum of graphene or graphite can appear fairly simple – usually consisting of only two main bands and a few more very small bands. However, these bands actually tell us quite a bit about the material. Figure 1 shows a typical Raman spectrum of graphite.
