Abstract
In these measurements we have investigated the time scale of the excitation of electrons leading to a transition from the quantum Hall state to the dissipative state in the two-dimensional electron system of GaAs/AlGaAs heterostructures with Corbino geometry. The breakdown of the quantum Hall effect occurs after a certain time (2 ≤ τ resp ≤ 20 ns) that is a function of applied voltage (pulse amplitude), magnetic field and electron mobility.
