Abstract

The present work aims at formulating hydrodynamic models for a proper description of charge transport in graphene, which is extremely important for growing technological development in CAD tools. The analysis is carried out in two different steps. Initially a semi-classical hydrodynamic model is developed starting from the moment system associated with Boltzmann equation and obtaining the closure relations with the Maximum Entropy Principle. At this level quantum effects are neglected. In the second step the model previously developed is extended to include quantum effects by incorporating the first order quantum corrections. To asses the validity of this model numerical simulations are under current investigation.
