Proposal for an Experimental Test of the Role of Confining Potentials in the Integral Quantum Hall Effect
arXiv:physics/0011056
Abstract
We propose an experiment using a three-gate quantum Hall device to probe the dependence of the integral quantum Hall effect (IQHE) on the shape of the lateral confining potential in edge regions. This shape can, in a certain configuration determine whether or not the IQHE occurs.
