Coulomb drag in graphene

Abstract

We calculate theoretically the Coulomb drag resistivity for two graphene monolayers spatially separated by a distance "$d$". We show that the frictional drag induced by inter-layer electron-electron interaction goes asymptotically as $T^2/n^3$ and $T^2\ln (n)/n$ in the high-density ($k_{F}d\gg 1$) and low-density ($k_{F}d\ll 1$) limits, respectively.
