Abstract
The low temperature magneto-resistance of quasi-ballistic, corrugated quantum wires has been studied. In the region near zero magnetic field , the magneto-resistance exhibits a series of clear oscillations which simulations reveal to be associated with multiple backscattering of e lectrons from the intentionally induced gate corrugation. This backsca ttering,in turn, gives rise to a strong scarring of the probability de nsity in the wire, the details of which are easily related to classica l scattering trajectories within it.
