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

Thermal properties of graphene and multilayer graphene: Applications in thermal interface materials
TL;DR: In this paper, the use of liquid-phase-exfoliated graphene and multilayer graphene as fillers in the thermal interface materials has been discussed, and it has been demonstrated that the addition of an optimized mixture of graphene and multi-layer graphene to the composites with different matrix materials produces the record-high enhancement of the effective thermal conductivity at the small filler loading fraction (f≤10vol%).

Solution Phase Production of Graphene with Controlled Thickness via Density Differentiation
TL;DR: Graphene flakes with controlled thicknesses are isolated in solution using density gradient ultracentrifugation, which results in graphene-surfactant complexes having buoyant densities that vary with graphene thickness.
