TLDR
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.Abstract:
Graphene is the two-dimensional building block for carbon allotropes of every other dimensionality We show that its electronic structure is captured in its Raman spectrum that clearly evolves with the number of layers The D peak second order changes in shape, width, and position for an increasing number of layers, reflecting the change in the electron bands via a double resonant Raman process The G peak slightly down-shifts This allows unambiguous, high-throughput, nondestructive identification of graphene layers, which is critically lacking in this emerging research arearead more

The quasi-free-standing nature of graphene on H-saturated SiC(0001)
Florian Speck,Johannes Jobst,Felix Fromm,Markus Ostler,Daniel Waldmann,Martin Hundhausen,Heiko B. Weber,Th. Seyller +7 more
TL;DR: In this paper, a quasi-free-standing graphene on 6H-SiC(0001) was obtained by intercalation of hydrogen under the buffer layer using infrared absorption spectroscopy.

Coherent and broadband enhanced optical absorption in graphene.
TL;DR: A broadband enhancement of the light absorption in graphene over the whole visible spectrum is experimentally demonstrated by using an Attenuated Total Reflectance (ATR) configuration and it is explained in terms of coherent absorption arising from interference and dissipation.

Atomically Thin MoS2: A Versatile Nongraphene 2D Material
TL;DR: In this paper, the progress in mono/few layer (s) MoS2 research is reviewed by focusing primarily on the layer dependent evolution of crystal, phonon, and electronic structure.
Journal ArticleDOI
Thermal and Thermoelectric Properties of Graphene
TL;DR: It is shown that the superior thermal conductivity of graphene is contributed not only by large ballistic thermal conductance but also by very long phonon mean free path (MFP), which results in important isotope effects and size effects on thermal conduction.

TL;DR: In this article, the Raman G peak of carbon fiber is studied in relation to applied strain and referenced to graphene; the work could facilitate stress measurements of carbon fibre polymer composites.
