Defect-induced Fermi level pinning and suppression of ambipolar behaviour in graphene

We report on systematic study of electronic transport behaviour of low-biased, disordered graphene nanowires. We reveal the emergence of unipolar transport as the defect concentration increases beyond 0.3% where an almost insulating behaviour is observed for n-type conduction whilst a metallic behav...
