Abstract
A statistical model is presented for a spatially inhomogenous two-dimensional electron gas (2DEG) in a quantizing magnetic field, which simulates the effects of Poisson’s equation and some essential properties of selfconsistent screening. The model yields an effective background density of states (DOS) between Landau levels (L.L.’s) and is used to explain a number of recent experimental observations. A three-dimensional model of a heterojunction is introduced, which can account for the possible charge transfer between the gate and the 2DEG.
