Abstract
Motivated by very recent studies of Coulomb drag in a graphene-BN-graphene system we develop a theory of Coulomb drag for the Fermi-liquid regime, for the case when the ratio of spacer thickness to the Fermi wavelength of electrons is arbitrary. The concentration () and thickness dependence of the drag resistivity is changed from for the thick spacer to for the thin one.
