Raman spectroscopy is an integral part of graphene research. It is used to determine the number and orientation of layers, the quality and types of edge, and the effects of perturbations, such as electric and magnetic fields, strain, doping, disorder and functional groups. This, in turn, provides insight into all sp(2)-bonded carbon allotropes, because graphene is their fundamental building block. Here we review the state of the art, future directions and open questions in Raman spectroscopy of…

Raman spectroscopy of graphene edges.

A detailed Raman investigation of graphene flakes with edges oriented at different crystallographic directions is presented and a real space theory for Raman scattering is developed to analyze the general case of disordered edges.

Quantifying defects in graphene via Raman spectroscopy at different excitation energies.

It is found that the ratio between the D and G peak intensities, for a given defect density, strongly depends on the laser excitation energy, and a simple equation for the determination of the point defect density in graphene via Raman spectroscopy is presented.

Raman study on the g mode of graphene for determination of edge orientation.

It is found that edge orientations could be identified by G mode in addition to D mode, which is well-explained by the unique properties of pseudospin at graphene edges, which lead to asymmetry of Raman active modes and non-adiabatic processes at different types of edges.

Raman spectrum of graphene and graphene layers.

This work shows that graphene's electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers, and allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research area.
