The largest transport band gap obtained in a suspended , highly functionalized ( I ( D ) / I ( G ) = 4 . 5 ) graphene is about 1 meV , lower than our theoretical predictions considering the quantum interference effect between two neighboring S - regions and attributed to its population with midgap states .
