In particular, the dynamics of an electron in a broadened Landau band not only depends on the disorder potential but also on the value of |£|. This leads to an I n dependence of the conductivities axx and oxy, which implies that the IQHE breaks down if |£| is sufficiently high. We show that the general form of the | El-dependence of axx and axy can lead to jumps in the longitudinal resistance at the breakdown of the IQHE, as observed in recent experi ments. | | | |
