摘要：
Motivated by recent experiments which found substantial disorder in graphene we discuss transport in the presence of weak and strong disorder on a honeycomb lattice. Assuming that disorder is mostly due to ripples in the graphene sheet, a model for random bonds is studied. Several approaches are discussed and their results in terms of the conductivity are compared. This leads to the conclusion that transport in graphene must be of diffusive nature.
