Multiscale Approaches for Electronic Device Simulation

Simulation of electronic devices relies to large extent on semi-classical models, especially the drift-diffusion model. Where quantum effects or atomistic details are particularly important, more involved models are used. Ideally, a combination of models on different scales would allow the simulation of the overall device structure. Here we present some approaches for combining continuum and atomistic models with the drift-diffusion model for the simulation of optoelectronic devices.
