Ballistic transport in graphene nanostrips in the presence of disorder: importance of edge effects

Nano Lett. 2007 Jan;7(1):204-10. doi: 10.1021/nl062132h.


Stimulated by recent advances in isolating graphene and similarities to single-wall carbon nanotubes, simulations were performed to assess the effects of static disorder on the conductance of metallic armchair- and zigzag-edge graphene nanostrips. Both strip types were found to have outstanding ballistic transport properties in the presence of a substrate-induced disorder. However, only the zigzag-edge strips retain these properties in the presence of irregular edges, making them better initial synthetic targets for ballistic device applications.
