  Charge carrier transport in single-layer graphene with one-dimensional
charged defects is studied theoretically. Extended charged defects, considered
an important factor for mobility degradation in chemically-vapor-deposited
graphene, are described by a self-consistent Thomas-Fermi potential. A
numerical study of electronic transport is performed by means of a
time-dependent real-space Kubo approach in honeycomb lattices containing
millions of carbon atoms, capturing the linear response of realistic size
systems in the highly disordered regime. Our numerical calculations are
complemented with a kinetic transport theory describing charge transport in the
weak scattering limit. The semiclassical transport lifetimes are obtained by
computing scattered amplitudes within the second Born approximation. The
transport electron-hole asymmetry found in the semiclassical approach is
consistent with the Kubo calculations. In the strong scattering regime, the
conductivity is found to be a sublinear function of electronic density and
weakly dependent on the Thomas-Fermi screening wavelength. We attribute this
atypical behavior to the extended nature of one-dimensional charged defects.
Our results are consistent with recent experimental reports.
