COULOMB DRAG IN THE BALLISTIC ELECTRON-TRANSPORT REGIME

We calculate the Coulomb drag current created in the ballistic transpo rt regime in a one-dimensional nanowire by a ballistic current in a ne arby nanowire. We predict sharp oscillations of the drag current as a function of the gate voltage or chemical potential. Our results may be of relevance to the issue of the cross-wire talk which is of pivotal importance to the proper operation of scaled-down devices and VLSI cir cuits.
