We propose a model for the numerical simulation of a two-terminal scanning gate spectroscopy experiment on bilayer graphene in the Quantum Hall regime. We start from the Chalker-Coddington random network model and link the model parameters with some of the relevant quantities in the experimental setup. The comparison between the simulation and the measurement results show a good qualitative and in...
We present a numerical investigation of the conductance and shot noise behavior of a cascade of realistic tunnel barriers, defined in a GaAs/AlGaAs heterostructure using negatively biased depletion gates. We show that, even in the presence of irregularities in the gate boundaries, strong localization dominates the transport through the device and consequently the shot noise suppression factor does...
