COULOMB INTERACTIONS AND THE INTEGER QUANTUM HALL-EFFECT - SCREENING AND TRANSPORT
We examine the influence of Coulomb interactions on the integer quantum Hall effect in high-mobility, wide spacer-layer heterostructures. In these devices, the potential due to disorder is expected to be smooth on the scale of the spacer-layer thickness, which can be much larger than the magnetic le...
