NANOSCALE TRANSISTORS: Device Physics, Modeling and Simulation describes the recent development of theory, modeling, and simulation of nanotransistors for electrical engineers, physicists, and chemists working with nanoscale devices. Simple physical pictures and semi-analytical models, which were validated by detailed numerical simulations, are provided for both evolutionary and revolutionary nanotransistors. Chapter 1 reviews some basic concepts, and Chapter 2 summarizes the essentials of traditional semiconductor devices, digital circuits, and systems. This material provides a baseline against which new devices can be assessed. Chapters 3 and 4 present a non-traditional view of the MOSFET using concepts that are valid at nanoscale. Chapter 5 applies the same concepts to nanotube FET as an example of how to extend the concepts to revolutionary nanotransistors. Chapter 6 explores the limits of devices by discussing conduction in single molecules.

Silicon CMOS technology continues to drive progress in electronics, but device scaling is rapidly taking the metal oxide semiconductor field-effect transistor (MOSFET) to its limit. A variety of new devices are emerging as candidates to replace MOSFETs and continue the trend downward to molecular dimensions. Nanoscale MOSFET engineering, is still governed by techniques originally developed to treat microscale devices. To push MOSFETs to their limits and to explore devices that may complement or even supplant them, this timely reference presents a clear understanding of device physics at the nano/molecular scale.
