SEM Images (IMAGE) Institute for Basic Science Caption These are SEM images of graphene domains growing. They showed that 2 seconds was enough for a domain to grow to ~400 μm and that ~1 mm domains were formed after 5 seconds. The statistical growth rate is more than three orders of magnitude faster than typical graphene growth and three times faster than the previous record realized with a continuous oxygen supply.
