In addition to its large scale in-plane properties, transport in (quasi) two-dimensional electron systems is sensitive to microscopic details in the transverse direction. An efficient tool to study the interplay between both is a parallel magnetic field, which probes the structure of wave functions perpendicular to the plane. Due to the Berry-Robnik symmetry effect, one finds that the magnetoresistance contains information on the geometry of the confining potential as well as characteristics of the disorder.
