TL;DR: In this paper, a systematic study of the ratio between the integrated intensities of the disorder-induced D and G Raman bands (ID∕IG) in nanographite samples with different crystallite sizes (La) and using different excitation laser energies is presented.

TL;DR: In this article, a superlattice-induced Raman scattering can be used to probe the phonon dispersion in twisted bi-layer graphene (tBLG), which is different from the broadly studied double-resonance in graphene-related materials in many aspects, and despite the absence of stacking order in tBLG, layer breathing vibrations (namely ZO' phonons) are observed.

TL;DR: This work studies single wall carbon nanotubes deposited on quartz and addresses the problem using electric force microscopy and ab initio calculations, both showing that the electronic properties along a single SWNT are being modulated via tube-substrate interaction.

TL;DR: In this paper, a phenomelogical model has been established to explain the evolution of the Raman spectrum of graphene with increasing amount of disorder caused by low energy ion bombardment.

TL;DR: In this article, micro-Raman spectroscopy was used to study silicone-based hydrogel polymers after being modified by 800 nm, 27 fs laser pulses from a Ti:sapphire oscillator at 93 MHz repetition rate.
