Creating nearly perfect meter sized graphene one hundred times faster

Researchers have achieved a leap forward in graphene production, from a technique that synthesizes a few square centimeters of single-crystal graphene in a couple of hours, to an optimized method that allows the creation of an almost-perfect (over 99.9 percent aligned) 5 × 50 cm2 single-crystal graphene in just 20 minutes.

The low production costs, comparable to commercially available lower quality polycrystalline graphene films, could expand its usability. The method is expected to stimulate further fundamental work on graphene and related materials, including large scale folding of graphene sheets, similar to paper, creating origami-like or kirigami-like shapes, which could be applied to future flexible circuits.
