Universal scaling of strong-field localization in an integer quantum Hall liquid
Universal scaling of strong-field localization in an integer quantum Hall liquid
We study the Landau level localization and scaling properties of a disordered two-dimensional electron gas in the presence of a strong external magnetic field. The impurities are treated as random distributed scattering centers with parameterized potentials. Using a transfer matrix for a finite-width strip geometry, we calculate the localization length …
