Graphene: Chemical Vapor Deposition of Graphene on Copper from Methane, Ethane and Propane: Evidence for Bilayer Selectivity (Small 9/2012)
The cover image shows a schematic pathway of how ethane gas can be used to grow AB-stacked, bilayer graphene through chemical vapor deposition on copper foils. The background is a selective area transmission electron microscopy image of bilayer graphene, and the foreground displays a scanning electron microscopy image of graphene with the bilayer regions–blue false-colored–lifted above to demonstrate the high bilayer coverage. The effects of different hydrocarbon gases have been studied to elucidate that the growth process of graphene on copper catalysts is not only based on the concentration of carbon in the reaction, but also on the different decomposition pathways of each hydrocarbon.

Weiller, and co-workers, beginning on page 1415.
