Classical electron dynamics influence behavior in long-range disordered samples.
Temperature-driven delocalization is affected by electron correlations.
Abstract
Recent work on the temperature-driven delocalization in the quantum Hall regime is reviewed, with emphasis on the role of electron-electron interactions and the correlation properties of disorder. We have stressed (i) the crucial role of the Coulomb interaction in the integer quantum Hall effect; (ii) the classical aspects of electron dynamics in samples with long-range disorder.
