Query: Quantized escape and formation of edge channels at high Landau levels   We present nonlocal resistance measurements in an ultra high mobility two
dimensional electron gas. Our experiments show that even at weak magnetic
fields classical guiding along edges leads to a strong non local resistance on
macroscopic distances. In this high Landau level regime the transport along
edges is dissipative and can be controlled by the amplitude of the voltage drop
along the edge. We report resonances in the nonlocal transport as a function of
this voltage that are interpreted as escape and formation of edge channels.
