  • Abstract
    The breakdown of the integral quantum Hall effect (IQHE) at high current is studied in wide high quality GaAs/AlGaAs heterostructures on the i=2 and i=4 Hall plateaux. Pronounced steps in the longitudinal resistance are observed with rich time structures, which are analyzed with different techniques.<>
