Abstract In the last few years, several methods have been proposed for the production of ultra-narrow stripes of graphene, called graphene nanoribbons, which could find several applications in nano- and opto-electronics. However, every production method gives rise to different types of ribbons, in terms of structural quality, width, edge pattern, and type of functional groups. In this review, we compare the Raman spectrum of graphene nanoribbons produced by different techniques by focusing on the effect of different structural parameters, such as width and edge-patterns. Effects due to changes in the lateral dimension are also discussed by comparing the Raman spectrum of ultra-narrow graphene nanoribbons with the spectrum of polycyclic aromatic hydrocarbons and defective graphene.
