Finite Element Solution of Optimal Control Problems Arising in Semiconductor Modeling |
Abstract | ||
---|---|---|
Optimal design, parameter estimation, and inverse problems arising in the modeling of semiconductor devices lead to optimization
problems constrained by systems of PDEs. We study the impact of different state equation discretizations on optimization problems
whose objective functionals involve flux terms. Galerkin methods, in which the flux is a derived quantity, are compared with
mixed Galerkin discretizations where the flux is approximated directly. Our results show that the latter approach leads to
more robust and accurate solutions of the optimization problem, especially for highly heterogeneous materials with large jumps
in material properties.
