New observations could improve industrial production of high-quality graphene, hastening the era of graphene-based consumer electronics. By combining data from several imaging techniques, engineers found that the quality of graphene depends on the crystal structure of the copper substrate it grows on. Copper with higher index numbers tends to have lower-quality graphene growth. Two common crystal structures, numbered (100) and (111), have the worst and the best growth, respectively.
