We study conductance fluctuations of the edge-state sheath that forms in the integer quantum Hall effect from the coupled edge states of a GaAs/Al x Ga 1-x As multilayer.

We have investigated mesoscopic conductance fluctuations in a GaAs quantum well with five electrically quantised two-dimensional (2D) subbands occupied. The conductance fluctuations occur even in a magnetic field p~rallei to the plane. We attribute the fluctuations to rapid electron-impurity scatter
