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...
One of the main drawbacks of undoped graphene for digital electronics applications is its am-bipolar behavior. Here we study the trasfer characteristics of transistors based on boron-doped graphene nanoribbons with atomic concentrations up to 0.6%, showing that the presence of doping generates a clear electron-hole transport asymmetry. In order to obtain these results, we introduce a method to accurately...
