A Spectral Method for the Numerical Simulation of Transit-Time Devices
For the numerical simulation of semiconductor devices driven by a periodic voltage a new numerical approach is presented. The method is based on a temporal Fourier expansion to solve time-dependent nonlinear partial differential equations like the Drift-Diffusion Model. Disadvantages and problems of conventionally used time discretizations are avoided. To achieve high-accuracy results an interval based error-analysis is presented.
