Researchers from the University of Illinois found out that the quality of graphene depends on the crystal structure of the copper substrate it grows on. Some copper structures results in high-quality graphene, and some do not. Obviously the higher-quality graphene is grown on more expensive and complicated structures...
The researchers now hope to use their methodology to study the growth of other two-dimensional materials, including insulators to improve graphene device performance.
