Construction of Stable Discretization Schemes for the Hydrodynamic Device Model

  • W. H. A. Schilders


Several authors have reported numerical problems when simulating semiconductor devices using the hydrodynamic model. In this paper, the cause of these numerical problems is identified. Furthermore, a remedy consisting of adaptive quadrature rules is proposed. The resulting discrete schemes are stable, which is verified both theoretically and demonstrated through several examples.
