Scattering Spectrum

Raman scattering spectrum of monolayer MoS2 shows anomalous enhanced peaks from 500 to 900 cm−1 for the 354 nm laser excitation, which can be explained by the double resonance Raman scattering process.

This article examines the optical properties of single-wall carbon nanotubes (SWNTs) and nanographene. It begins with an overview of the shape of graphene and nanotubes, along wit the use of Raman spectroscopy to study the structure and exciton physics of SWNTs. It then considers the basic definition of a carbon nanotube and graphene, focusing on the crystal structure of graphene and the electronic structure of SWNTs, before describing the experimental setup for confocal resonance Raman spectroscopy. It also discusses the process of resonance Raman scattering, double-resonance Raman scattering, and the Raman signals of a SWNT as well as the dispersion behavior of second-order Raman modes, the doping effect on the Kohn anomaly of phonons, and the elastic scattering of electrons and photons. The article concludes with an analysis of excitons in SWNTs and outlines future directions for research.
