Abstract
We have studied the commensurability oscillations for a nonplanar, two-dime nsional electron gas which is confined to a surface spatially modulated bot h in the transverse and longitudinal directions. We show, numerically, that coupling the drift in both directions causes the motion to be chaotic. The channeling tori, responsible for conduction along the stripes, are destroy ed and the averaged squared drift velocities decrease. (C) 1999 Academic Pr ess.
