Charged-impurity scattering in graphene
&
Abstract
Since the initial demonstration of the ability to experimentally isolate a single graphene sheet, a great deal of theoretical work has focused on explaining graphene|[rsquo]|s unusual carrier-density-dependent conductivity |[sigma]|(n), and its minimum value (|[sigma]|min) of nearly twice the quantum unit of conductance (4e2/h) (refs|[nbsp]|1, 2, 3, 4, 5, 6). Potential explanations for such behaviour include short-range disorder, |[lsquo]|ripples|[rsquo]| in graphene|[rsquo]|s atomic structure and the presence of charged impurities.
