dc.description.abstract Quantum Hall samples with Corbino geometry show an enhanced hysteresis of the I-V curves near the breakdown of the Quantum Hall effect at low AC frequencies. We explain this finding within a hot-electron model by an assumed reduction of the subcritical conductivity σxx (under non-equilibrium conditions) with frequency. In this study, we present measurements of σxx as a function of the frequency on various samples. The observed drop of the subcritical σxx with frequency is of the same order as predicted and proves therefore our model. © 2005 American Institute of Physics. eng
