Oxygen Control of Graphene Growth The growth of graphene on copper surfaces through the decomposition of hydrocarbons such as methane can result in a wide variety of crystal domain sizes and morphologies. Hao et al. (p. 720, published online 24 October; see the cover) found that the presence of surface oxygen could limit the number of nucleation sites and allowed centimeter-scale domains to grow through a diffusion-limited mechanism. The electrical conductivity of the graphene was comparable to…

The physicochemical mechanisms underlying the nucleation and growth kinetics of graphene on copper are studied, providing new insights necessary for the engineering synthesis of wafer-scale single crystals.
Influence of copper morphology in forming nucleation seeds for graphene growth.
TLDR
Although the best monolayer graphene was grown from polished Cu with a low sheet resistance of 260 Ω/sq, a small portion of multilayers were also formed near the impurity particles or locally protruded parts.

Evolution of graphene growth on Ni and Cu by carbon isotope labeling.
TLDR
This work used carbon isotope labeling in conjunction with Raman spectroscopic mapping to track carbon during the growth process and shows that at high temperatures sequentially introduced isotopic carbon diffuses into the Ni first, mixes, and then segregates and precipitates at the surface of Ni forming graphene and/or graphite.

Interestingly, graphene syntheses using a Cu catalyst in APCVD processes at higher methane concentrations revealed that the growth is not self-limiting, which is in contrast to previous observations for the LPCVD case.
