Mathematical modelling of charge transport in graphene heterojunctions
Luigi Barletti, Giovanni Nastasi, Claudia Negulescu +1
A typical graphene heterojunction device can be divided into two classical zones, where the transport is basically diffusive, separated by a "quantum active region" (e.g., a locall…

Quantum transmission conditions for diffusive transport in graphene with steep potentials
Luigi Barletti, Claudia Negulescu
We present a formal derivation of a drift-diffusion model for stationary electron transport in graphene, in presence of sharp potential profiles, such as barriers and steps. Assumi…
