@article{Yang2000StudyOU, title={Study of universality at integer quantum Hall transitions}, author={Kun Yang and Dan Shahar and Ravindra N. Bhatt and Daniel C. Tsui and Mansour Shayegan}, journal={Journal of Physics: Condensed Matter}, year={2000}, volume={12}, pages={5343-5360} }

We report in this paper results of experimental and theoretical studies of transitions between different integer quantum Hall phases in two-dimensional electron systems, as well as the transition to the insulating phase at high magnetic fields. We focus mainly on the resistivity at the transitions. We first present results of a numerical calculation for a non-interacting electron model, which shows that the Thouless conductance is universal at integer quantum Hall transitions, just like the…
