Zigzag Orientation of Graphene This layout has proven to always be metallic no matter how thin the ribbon is. It is the only orientation that shows the characteristic of being purely metallic.

Graphene and a Band Structure The 6 corners hexagonal Brillouin zone have a linear band structure Meaning that electrons and holes have effective mass of 0 This leads the particles to act like a relativistic particles according to the Dirac equation When graphene is cut or grown into nanoribbons a band gap opens up
