27 Jul 2006 | Journal: | Physica E, vol. 34, pg 136-139, 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect | Abstract: | We report on theoretical and experimental investigations of a novel hysteresis effect that has been observed on the magnetoresistance of quantum-Hall bilayer systems. Extending to these system a recent approach, based on the Thomas-Fermi-Poisson nonlinear screening theory and a local conductivity model, we are able to explain the hysteresis as being due to screening effects such as the formation of ``incompressible strips’’, which hinder the electron density in a layer within the quantum Hall regime to reach its equilibrium distribution. | Source: | arXiv, cond-mat/0607724 | Services: | Forum | Review | PDF | Favorites |
