To push MOSFETs to their scaling limits and to explore devices that may complement or even replace them at molecular scale, a clear understanding of device physics at nanometer scale is necessary. Nanoscale Transistors provides a description on the recent development of theory, modeling, and simulation of nanotransistors for electrical engineers, physicists, and chemists working on nanoscale devices. Simple physical pictures and semi-analytical models, which were validated by detailed numerical simulations, are provided for both evolutionary and revolutionary nanotransistors. After basic concepts are reviewed, the text summarizes the essentials of traditional semiconductor devices, digital circuits, and systems to supply a baseline against which new devices can be assessed. A nontraditional view of the MOSFET using concepts that are valid at nanoscale is developed and then applied to nanotube FET as an example of how to extend the concepts to revolutionary nanotransistors. This practical guide then explore the limits of devices by discussing conduction in single molecules

This book consists of four chapters to address at different modeling levels for different nanoscale MOS structures (Single- and Multi-Gate MOSFETs). The collection of these chapters in the book are attempted to provide a comprehensive coverage on the different levels of electrostatics and transport modeling for these devices, and relationships between them. In particular, the issue of quantum transport approaches, analytical predictive 2D/3D modeling and design-oriented compact modeling. It should be of interests to researchers working on modeling at any level, to provide them with a clear explanation of theapproaches used and the links with modeling techniques for either higher or lower levels.

Terahertz (THz) electromagnetic waves, phenomena in the THz range and related technological issues have been explosively investigated during the recent two decades. However, its potential as a disruptive technology to commercial applications has yet to make any impression.The Russia-Japan-USA-Europe Symposium on Fundamental and Applied Problems of Terahertz Devices and Technologies (RJUSE-TeraTech 2016), held at Katahira Campus of Tohoku University, Sendai, Japan on October 31 - November 4, 2016, aims to bring together researchers from Russia, Japan, USA and Europe, who are working on the broad range of related problems in the terahertz devices, technologies and applications, to discuss on state-of-the-art results and future directions and collaborations in the development of THz.This is the fifth in the series of preceding successful symposiums in Terahertz Devices and Technologies. It contains 14 selected extended papers presented at the RJUSE-TeraTech 2016 symposium, addressing the variety of topics, in particular, THz detectors based on double heterojunction bipolar transistors (DHBT) and field effect transistors (FET) utilizing resonant plasma effects, quantum cascade (QCL) and HgCdTe quantum-well heterostructures, and graphene-based THz devices.

This book brings together seven selected best papers presented at the 2014 Russia-Japan-USA Symposium on Fundamental and Applied Problems of Terahertz Devices and Technologies (RJUS TeraTech-2014), which was held at the University of Buffalo, New York, USA on 17-21 June 2014.As the third in the series of annual meetings, RJUS TeraTech-2014 continues to be an excellent platform for researchers to exchange their recent original results, and to deal with the technical challenges and barriers of transitioning the research results into the THz system-level applications. The symposium focuses on 2 main areas, namely, interaction of THz radiation with micro- and nano-structures, and advanced solid-state THz emitters and sensors. Leading experts from academia, industry, and government agencies from three countries, including USA, Japan, and Russia, contributed to the collection of research results and developments.This book, covering issues ranging from basic Thz-related phenomena to applications in sensing, imaging, and communications, contains some ground-breaking works in the industry, and will be a useful reference for device and electronics engineers and scientists.

This book constitutes the thoroughly refereed post-conference proceedings of 19th International Workshop on Power and Timing Modeling, Optimization and Simulation, PATMOS 2009, featuring Integrated Circuit and System Design, held in Delft, The Netherlands during September 9-11, 2009. The 26 revised full papers and 10 revised poster papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on variability & statistical timing, circuit level techniques, power management, low power circuits & technology, system level techniques, power & timing optimization techniques, self-timed circuits, low power circuit analysis & optimization, and low power design studies.

This book provides unique perspectives on both state-of-the-art hyperspectral techniques for the early-warning monitoring of water supplies against chemical, biological and radiological (CBR) contamination effects as well as the emerging spectroscopic science and technology base that will be used to support an array of CBR defense and security applications in the future. The technical content in this book lends itself to the non-traditional requirements for point and stand-off detection that have evolved out of the US joint services programs over many years. In particular, the scientific and technological work presented seeks to enable hyperspectral-based sensing and monitoring that is real-time; in-line; low in cost and labor; and easy to support, maintain and use in military- and security-relevant scenarios.
