Structures in the Breakdown Curves of the Quantum Hall Effect in Narrow Channel GaAs/AlGaAs Heterostructures
Measurements of the breakdown of the quantum Hall effect (Q.H.E.) have been made on single heterostructures with a narrow constriction (∼2 μm). Structures corresponding to sharp increases in dissipation were observed in both the source-drain current sweeps at constant magnetic field and the magnetic field sweeps at constant source-drain current.
