Scattering-free bulk transport occurs across a two-dimensional conductor in the quantized Hall regime, confirming current flow through inner incompressible strips.
Direct electrical measurement across a Hall bar geometry with a central contact directly detects dissipationless current flowing well away from the outer edges.
Supports the screening theory over the standard Landauer-Buttiker picture, confirming that electron-electron interactions shift conductive paths into the bulk.
