Conductance quantization suppression in the quantum Hall regime

Conductance quantization suppression in the quantum Hall regime

Conductance quantization is the hallmark of non-interacting confined systems. The authors show that the quantization in graphene nanoconstrictions with low edge disorder is suppressed in the quantum Hall regime. This is explained by the addition of new conductance channels due to electrostatic scree...
