Abstract
We derive an empirical formula for the width of quantum Hall effect plateaus which is free of adjustable parameters. It describes the integer, fractional and (Wigner insulator) quantum Hall effect in single heterojunctions. The temperature scale of the existence of these three phenomena is the same as the melting temperature of a classical Wigner crystal. We conclude that the basic assumption of the current theory of QHE that the plateau width is determined by the disorder is highly improbable.
