Abstract / Description:Using a new MBE growth technique, we fabricate a two-dimensional
electron system which is bent around an atomically sharp 90degrees
corner. In the quantum Hall regime under tilted magnetic fields, we can
measure equilibration between both co- and counter-propagating edge
channels of arbitrary filling factor ratio. We present here
4-point-magnetotransport characterization of the comer junction with
unequal filling factor combinations which can all be explained using
the standard Landauer-Buttiker edge channel picture. The success of
this description confirms the realization of the first non-planar
quantum Hall edge geometry. (C) 2003 Elsevier B.V. All rights reserved.
