Because of it's high ultimate tensile strength, a single atomic layer of graphene has been able to suspend micron size holes reliably. However, to extend into regimes where devices have dimensions measured in millimeters, a single layer of graphene is insufficient. Films made from a few layers of graphene, although not as strong as pristine single layer graphene, have been shown to still retain a high level of strength. Using chemical vapor deposition on a nickel catalyst, we have fabricated many layer graphene films and suspended these membranes over millimeter size holes. Mechanical properties were measured on suspended films using a custom bulge test instrument.
