By selectively populating spin resolved edge channels using Schottky gates we experimentally investigate the transition from adiabatic to equilibrated transport in the Quantum Hall regime. The scattering processes within a contact e. g. provide an excellent possibility to equilibrate nonequally populated edge channels. Here we demonstrate that not only with metallic reservoirs but also with ...
