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 …

Recent Raman scattering studies in different types of graphene samples are reviewed here.
We first discuss the first-order and the double resonance Raman scattering mechanisms in …

We present a Raman study of Ar+-bombarded graphene samples with increasing ion doses.
This allows us to have a controlled, increasing, amount of defects. We find that the ratio …

In this article we review Raman studies of defects and dopants in graphene as well as the
importance of both for device applications. First a brief overview of Raman spectroscopy of …

This paper reviews progress that has been made in the use of Raman spectroscopy to study
graphene and carbon nanotubes. These are two nanostructured forms of sp2 carbon …

Graphene has many unique properties that make it an ideal material for fundamental studies
as well as for potential applications. Here we review recent results on the Raman …

Raman spectroscopy is the inelastic scattering of light by matter. Being highly sensitive to
the physical and chemical properties of materials, as well as to environmental effects that …

Graphene is a two-dimensional material defined as a planar honeycomb lattice of close-
packed carbon atoms, where the electrons exhibit a linear dispersion near Dirac K points …

Step-by-step controllable thermal reduction of individual graphene oxide sheets,
incorporated into multiterminal field effect devices, was carried out at low temperatures …

We report the production of a two-dimensional (2D) heterostructured gas sensor. The gas-
sensing characteristics of exfoliated molybdenum disulfide (MoS2) connected to …
