Graphene and related 2D materials: An overview of the Raman studies

Abstract

After a brief overview of the discovery and the Raman study of new forms of carbons (intercalated graphite, carbon fiber, fullerenes, carbon nanotubes), the invaluable contribution of late Professor M. Dresselhaus is noted, and the 10 reviews and 9 contributions collected to present a picture of the current Raman investigations of graphene and related 2D materials (such as black phosphorus, MoS2) are introduced. Methods for numbering the graphene layers, the effects of external perturbations (temperature, pressure, doping, and magnetic field) on the phonons of graphene, characterization of the chemical and structural properties of graphene at the nanoscale level by tip-enhanced Raman spectroscopy, surface enhanced Raman spectroscopy and hyperspectral imaging, and applications combining graphene and Raman spectroscopy are addressed.
