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

TL;DR: It is shown that a hybrid material made out of a few phosphorene layers sandwiched between graphene layers shows a specific capacity of 2,440 mA h g(-1) at a current density and an 83% capacity retention after 100 cycles while operating between 0 and 1.5 V.

Graphene Thickness Determination Using Reflection and Contrast Spectroscopy
TL;DR: Two easy-to-use methods to determine the number of graphene layers based on contrast spectra are provided: a graphic method and an analytical method, which show that the refractive index of graphene is different from that of graphite.
