Phys. Rev. Lett. 101, 196803 (2008) [4 pages]Adsorbate-Limited Conductivity of GrapheneReceived 18 August 2008; published 5 November 2008 We present a theory of electronic transport in graphene in the presence of randomly placed adsorbates. Our analysis predicts a marked asymmetry of the conductivity about the Dirac point, as well as a negative weak-localization magnetoresistivity. In the region of strong scattering, renormalization group corrections drive the system further towards insulating behavior. These results explain key features of recent experiments, and are validated by numerical transport computations. © 2008 The American Physical Society URL:
