Friedel Oscillations, Impurity Scattering, and Temperature Dependence of Resistivity in Graphene
Friedel Oscillations, Impurity Scattering, and Temperature Dependence of Resistivity in Graphene
We show that Friedel oscillations (FO) in grapehene are strongly affected by the chirality of electrons in this material. In particular, the FO of the charge density around an impurity show a faster, $1/r^3$, decay than in conventional 2D electron systems and do not contribute to a linear temperature-dependent correction …
