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

Graphene defect engineering for optimizing the interface and mechanical properties of graphene/copper composites
TL;DR: In this paper, a rational defect engineering strategy was proposed to tailor the interface and mechanical properties of graphene/Cu composites, and the composites with plasma-treated graphene exhibited a higher strength enhancement and better interface stability in response to thermal cycling, which was attributed to the CuxOy-coordinated improved interfacial bonding that provided efficient load transfer and thermal stress relaxation.

High-quality and efficient transfer of large-area graphene films onto different substrates
TL;DR: In this paper, a two-layer structure consisting of polyethylene terephthalate (PET) and silicone was used to transfer graphene grown by chemical vapor deposition onto various rigid and flexible substrates through dispersive adhesion.
