Description
The quantum hall effect (QHE) is an important topic for those studying the way electrons move in materials, particularly in structures that confine such a movement in one or more dimensions (low-dimensional structures). This book provides an introduction to the ways of using the various models that try to explain diverse aspects of the QHE, an effect that is still not properly understood. Some chapters, such as "critical phenomena" and "multifractal analysis" should be of interest to a wider audience than those studying QHE.
