Hydrodynamical models are suitable to describe carrier transport in submicron semiconductor devices.
These models have the form of nonlinear systems of hyperbolic conservation laws with source terms, coupled to a Poisson equation. Transient results show the evolution of highly nonlinear waves emanating from the neibourhood of the junctions.
