This text treats the modeling and simulation of semiconductor devices in the quantum regime with particles, beginning with the early, and current, views of particles in quantum mechanics, and the full quantum mechanical approaches that make full use of this particle approach. Particle-based simulation techniques of quantum devices have the additional advantage of providing very simple and intuitive ways of understanding the transport of electrons, allowing a demystifying view of quantum phenomena in semiconductor devices. This is the first book to combine quantum transport and particle Monte Carlo techniques with a focus on modern semiconductor devices. Written in clear and accessible language suitable for graduate students, formal and technical details are included in several appendices, and a list of exercises and references for further reading are added at the end of each chapter.
