The integral quantumHalleffect (IQHE) has been investigated in GaAsGaAlAs heterostructures in the temperature range 0.1 ⩽ T ⩽ 4.2 with magnetic fields B ⩽ 8.5T. The source-drain conductivity has been measured in alternating current regime at frequencies from 0 up to 1 GHz. Distortion of the Hall-plateaux has been observed. The phenomenon is connected to a drift of electrons and holes cyclotron orbits in magnetic field along closed equipotential trajectories on the relief of a random potential.

Abstract
The integral quantumHalleffect (IQHE) has been investigated in GaAsGaAlAs heterostructures in the temperature range 0.1 ⩽ T ⩽ 4.2 with magnetic fields B ⩽ 8.5T. The source-drain conductivity has been measured in alternating current regime at frequencies from 0 up to 1 GHz. Distortion of the Hall-plateaux has been observed. The phenomenon is connected to a drift of electrons and holes cyclotron orbits in magnetic field along closed equipotential trajectories on the relief of a random potential.File in questo prodotto:
