About the Book:

The purpose of this book is to introduce interested scientists from academia and industry to advanced simulation methods needed for modeling state-of-the-art nanoscale devices.
The book also serves as a textbook for two graduate-level modeling classes: one devoted to semiclassical transport modeling and the second dedicated completely to quantum transport modeling. This book provides an overview of the basic techniques used in the field of computational electronics related to device simulation.
