Abstract
We discuss first hierarchical error estimates and a criterion for mesh refinement. Then we describe briefly the hydrodynamic model of semiconductor model. Based on artificial viscosity technique about electron velocity, we propose to solve a Poisson equation to obtain a correction about mesh optimization. Finally, we simulate a GaAs MESFET's device with a gate of 0.3 µm length and give some discussions about numerical results. Copyright © 2004 John Wiley & Sons, Ltd.
