Abstract

The single-particle energy spectrum of a two-dimensional electron gas in a perpendicular magnetic field consists of equally spaced energy states, known as Landau levels. Each level is split owing to spin interactions, and its degeneracy is proportional to the magnetic field strength. When the ratio, nu (or 'filling factor'), of the number of electrons and the degeneracy of a Landau level takes an ...
