| Abstract: | The three dimensional problem for the transient behavior of semiconductor with heat conduction is considered.Central difference schemes for the electric potential and heat conduction equations with implicit modified upwind difference schemes for the electron and hole concentration equations are provided.Linear extrapolations are used to treat different time steps.Convergence of the schemes are proved. |
