A guide to and review of the use of Multiwavelength Raman Spectroscopy for characterizing defective aromatic carbon solids: From graphene to amorphous carbons

sp2 hybridized carbons constitute a broad class of solid phases composed primarily of elemental carbon and can be either synthetic or naturally occurring. Some examples are graphite, chars, soot, graphene, carbon nanotubes, pyrolytic carbon, and diamond-like carbon. They vary from highly ordered to completely disordered solids and detailed...
