  We report the observation of Coulomb drag between a two-dimensional (2D)
electron gas in graphene and a one-dimensional (1D) wire composed of a carbon
nanotube. We find that drag occurs when the bulk of graphene is conducting, but
is strongly suppressed in the quantum Hall regime when magnetic field confines
conducting electrons to the edges of graphene and far from the nanotube.
Out-of-equilibrium and non-linear drag measurements show intriguing interplay
between 1D and 2D conductors. These hybrid electronic devices of novel geometry
could lead to potential applications for Van der Waals electronics
