Contribution

It provides new insights into the role of extended charge defects in graphene's transport properties, emphasizing their importance at low energies.

Findings

Extended charge defects strongly interact with Dirac fermions.

Defects significantly affect DC-conductivity in graphene.

Defects are common due to lattice mismatch in grown samples.

Abstract

We study the effect of extended charge defects in electronic transport properties of graphene. Extended defects are ubiquitous in chemically and epitaxially grown graphene samples due to internal strains associated with the lattice mismatch. We show that at low energies these defects interact quite strongly with the 2D Dirac fermions and have an important effect in the DC-conductivity of these materials.
