Computational electronics refers to the physical simulation of semiconductor devices in terms of charge transport and the corresponding electrical behavior. It is related to process simulation, which deals with various physical processes such as material growth, oxidation, impurity diffusion, etching, and metal deposition inherent in device fabrication. Device simulation can be thought of as one component of technology for computer-aided design (TCAD), which deals with compact behavioral models for devices and sub-circuits relevant for circuit simulation in commercial packages. The goal of this book is to provide simulation tools that capture the essential physics while at the same time minimizing the computational burden so that results are obtained within a reasonable time frame.
