Creation of the Most Perfect Graphene
New discovery allows for scalable production of fold-free and ad-layer free single-crystal graphene
A team of researchers led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS), including graduate students at the Ulsan National Institute of Science and Technology (UNIST), have achieved growth and characterization of large area, single-crystal graphene that has no wrinkles, folds, or adlayers. It can be said to be the most perfect graphene that has been grown and characterized, to date.
Director Ruoff notes, “This pioneering breakthrough was due to many contributing factors, including human ingenuity and the ability of the CMCM researchers to reproducibly make large-area single-crystal Cu-Ni(111) foils, on which the graphene was grown by chemical vapor deposition (CVD) using a mixture of ethylene with hydrogen in a stream of argon gas.” Student Meihui Wang, Dr. Ming …
