Wake effect in interactions of dipolar molecules with doped graphene
Abstract
We study the wake effect in the charge carrier density in free graphene induced by an electric dipole moving parallel to it by using the dynamic polarization function of graphene within the random phase approximation for its pi electrons described as Diracs fermions. We show that, while the equilibrium doping density of graphene sets a length scale for the period of the wake via graphenes Fermi wavenumber, qualitative properties of the wake are strongly affected by the speed of the dipole, its distance from graphene, and the dipole moment orientation.
