TL;DR: 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.

Large-scale pattern growth of graphene films for stretchable transparent electrodes
Keun Soo Kim,Yue Zhao,Houk Jang,Sang Yoon Lee,Jong Min Kim,Kwang S. Kim,Jong Hyun Ahn,Philip Kim,Philip Kim,Jae-Young Choi,Byung Hee Hong +10 more
TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.
