Abstract
An extended network model of the transition regime between two integer quantum Hall plateaus is presented. When it is used to analyze experimental data, two parameters of interest are extracted: the resistivity of the bulk conducting channel due to the energetically topmost Landau level and the scattering length between the bulk channel and the edge channels. The behavior of the equilibration length is studied for transitions between the two spin states of a given Landau level and between Landau levels with different quantum numbers. In some non-ideal devices, the nonlocal aspects of the transition regime cause dramatic and non-intuitive device behavior.
