摘要
A method of making graphene includes providing a seed gas in the presence of a metallic substrate, providing a pulsed, ultraviolet laser beam, and moving the substrate or the laser beam relative to the other, thereby advancing a graphene crystallization front and forming an ordered graphene structure. In some instances, the substrate can have a surface with two-fold atomic symmetry. A method of recrystallizing graphene includes providing a pulsed, ultraviolet laser beam to a polycrystalline graphene sheet.
