Method for synthesizing large area graphene using pulsed laser on metal crystalline substrate

摘要

A method for producing graphene, the step of supplying a seed gas in the presence of a metal substrate, the step of supplying a pulsed ultraviolet laser beam, and moving one of the substrate or the laser beam relative to the other, A step of advancing the crystallization front end to form a regular graphene structure. In one example, the substrate may have a two-fold symmetry plane. A method for recrystallization of graphene, which includes a step of supplying a pulsed ultraviolet laser beam to a polycrystalline graphene sheet.
