Response of Landau energy levels to the change of magnetic flux in non-isotropic impurities

Abstract

We have studied a practical approach for the inclusion of non-isotropic impurities in the systems showing integer quantum Hall effect. We observe that if the impurity distribution in the direction which the electric field applys, then the localized levels goes out from the origin with respect to the isotropic case, and the Hall step will the clearly observed.
