Raman scattering is used to study the effect of low energy (90 eV) Ar + ion bombardment in graphene samples as a function of the number of layers N. The evolution of the intensity ratio between the G band (1585 cm − 1) and the disorder-induced D band (1345 cm − 1) with ion fluence is determined for mono-, bi-, tri- and ∼ 50-layer graphene samples, providing a spectroscopy-based method to study the penetration of these low energy Ar + ions in AB Bernal stacked graphite, and how they affect the… 

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.

Modification on Single-Layer Graphene Induced by Low-Energy Electron-Beam Irradiation

In this work, we present studies of the effects of electron-beam irradiation on the modification of single-layer graphene. Micro-Raman spectra show that the D, D′, and D + G Raman bands, which are

Defect characterization in graphene and carbon nanotubes using Raman spectroscopy

This review discusses advances that have been made in the study of defect-induced double-resonance processes in nanographite, graphene and carbon nanotubes, mostly coming from combining Raman

Measuring disorder in graphene with the G and D bands

Here we analyse the evolution of the disorder induced D‐band (∼1350 cm−1) and of the first‐order allowed G‐band (∼1584 cm−1) in the Raman spectra of ion bombarded graphene. By increasing the

Investigation of n-Layer Graphenes as Substrates for Raman Enhancement of Crystal Violet

In this work, Raman signals from crystal violet (CV) molecules on n-layer graphenes are clearly observed while these signals are invisible on SiO2/Si substrate under the same deposition condition

Defect formation in graphene during low-energy ion bombardment

This letter reports on a systematic investigation of sputter induced damage in graphene caused by low energy Ar+ ion bombardment. The integral numbers of ions per area (dose) as well as their

Tunability of electronic properties of graphene is one of the most promising properties to integrate it to high efficiency devices in the field of electronics. Here we demonstrate the substrate



Raman spectroscopy study of Ar+ bombardment in highly oriented pyrolytic graphite

In this work, we discuss the effect of low energy Ar+ ion bombardment on highly oriented pyrolytic graphite (HOPG). The evolution of the G and D peak intensities are analyzed as a function of ion

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.

Phonon anharmonicities in graphite and graphene.

In graphene, the phonon anharmonic lifetimes and decay channels of the A(1)' mode at K dominate over E(2g) at Gamma and couple strongly with acoustic phonons, highlighting how ballistic transport in carbon-based interconnects requires careful engineering of phonon decays and thermalization.

Scattering and Interference in Epitaxial Graphene

It is shown that, when its source is atomic-scale lattice defects, wave functions of different symmetries can mix and reflect both intravalley and intervalley scattering.

Effect of exciton-phonon coupling in the calculated optical absorption of carbon nanotubes.

It is found that the optical properties of carbon nanotubes reflect remarkably strong effects of exciton- phonon coupling, and a significant fraction of the spectral weight of the absorption peak is transferred to a distinct exciton+phonon sideband, which is peaked at around 200 meV above the main absorption peak.

Electronic properties of graphene

Graphene is the first example of truly two‐dimensional crystals – it's just one layer of carbon atoms. It turns out that graphene is a gapless semiconductor with unique electronic properties
