Nanostructured graphene is a promising candidate for future devices at the nanometer scale. Defects and disorder as well as irregular edges cannot be avoided in any realistic setup. We use a l-orbital model for a systematic study of the effects of various kinds of defects on the electronic transport properties of graphene nanoribbons and emphasize differences and similarities to the well known results for carbon nanotubes.
