The dynamics of composite fermions in the ballistic transport regime in etched semiconductor nanostructures, imposed on a two-dimensional electron gas, has been investigated around half Landau level filling. The non-uniform electrostatic potential in the vicinity of soft walls in such etched nanostructures has a strong repercussion on the trajectories described by the quasi-particles. A ...
