Nano-Electronic Devices

This exhaustive survey of advanced simulation methods for modeling nanoscale devices systematically covers both theoretical approaches and numerical solutions, links methodology with the type of device, and includes advice on state-of-the-art semiconductors.

This book surveys the advanced simulation methods needed for proper modeling of state-of-the-art nanoscale devices. It systematically describes theoretical approaches and the numerical solutions that are used in explaining the operation of both power devices as well as nano-scale devices. It clearly explains for what types of devices a particular method is suitable, which is the most critical point that a researcher faces and has to decide upon when modeling semiconductor devices.

Provides a thorough overview of the methodologies that have been used in modeling longer channel length, nanoscale devices, are currently being used in understanding the operation and in design of nanoscale devices and should be used in design of ultra small scale future technology devices Offers expert guidance as to which modeling methods are most appropriate, given particular application types Includes systematic and detailed coverage of modeling with particle-based simulations, density matrix method, Wigner function approach, Greenâ™s functions approach, and atomistic simulations Includes supplementary material: sn.pub/extras

Klappentext
This book describes the state of the art in transport modeling, relevant for the simulation of nanoscale semiconductor devices. It systematically explains theoretical approaches and numerical solutions that are used in explaining the operation of both power devices and nano-scale devices. It clearly explains for what types of devices a particular method is suitable, which is the most critical point that a researcher faces and has to decide upon when modeling semiconductor devices. This book compiles different approaches to the problem of transport in mesoscopic semiconductor systems, ranging from semi-classical to fully quantum mechanical, in order to understand the advantages and limitations of each, as well as elucidating the complex and interesting phenomena encountered in ultra-small devices.
