Quantum Hall Effect: Current Distribution and Existence of Extended States
K. Tsemekhman, V. Tsemekhman, C. Wexler
We present a consistent description of the current distribution in the quantum Hall effect, based on two main ingredients: the location of the extended states and the distribution…

Density of states, screening and the width of the quantum Hall plateaus
K. Tsemekhman, V. Tsemekhman, C. Wexler
We present a consistent treatment of the quantum Hall effect within the electrostatic approximation. We derive the form of the density of states (DOS) which differs from the usual…

Quantum Hall Effect: Current Distribution and the Role of Measurement
K. Tsemekhman, V. Tsemekhman, C. Wexler +1
Based on very general arguments we show that for any geometry of the experiment, in the regime when the measurement leads to a quantized Hall conductivity, almost the entire curren…
