Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Graphene-based materials exhibit remarkable electronic, optical, and mechanical
properties, which has resulted in both high scientific interest and huge potential for a variety …

We study the transformation from molecular to crystalline of (non-) graphitic carbons
synthesized from organic precursors by heat-treatment. Easy assessment of structural …

Raman spectra of graphene oxides (GOs) with different chemical compositions and
synthesized by oxidation of distinct starting materials were analyzed to relate the spectral …

We determine the effect of defects induced by ion bombardment on the Raman spectrum of
single-layer molybdenum disulfide. The evolution of both the linewidths and frequency shifts …

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 …

sp 2 hybridized carbons constitute a broad class of solid phases composed primarily of
elemental carbon and can be either synthetic or naturally occurring. Some examples are …

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 …

The Raman scattering of single-and few-layered WS2 is studied as a function of the number
of SWS layers and the excitation wavelength in the visible range (488, 514 and 647 nm). For …

Graphene oxide (GO) prepared from graphite powder using a modified Hummers method
and reduced graphene oxide (rGO) obtained from GO using different reductants, ie, sodium …
