Method of making graphene and graphene devices

A graphene device, comprising:

• a precursor graphene device and a graphene layer,
• wherein the precursor graphene device comprises:
• an insulator layer, wherein at least the top portion of the insulator layer is an electrical insulator;
• a metal layer in contact with and covering part of the top of the insulator layer;
• and a carbon layer in contact with the metal layer and on top of the insulator layer,
• further wherein the graphene layer is in contact with the metal layer and the top of the insulator layer.
