There is a growing understanding that the progress of the conventional silicon technology will reach its physical, engineering and economic limits in about a decade. What will take us beyond 2010 are new molecular and other nanotechnologies that require the efforts of trans-disciplinary teams of physicists, quantum chemists, material and computer scientists, and engineers. This volume represents a unique collection of interdisciplinary review and original papers by experts in molecular nanowires, carbon nanotubes, mesoscopic super- and semiconductors, and theorists in the field of strongly correlated electrons and phonons. Topics include molecular nanojunctions and electronics, mesoscale semiconductors and superconductors, carbon nanotubes, low dimensional conductors, polarons and strongly-correlated electrons in nanoobjects, quantum theory of nanoscale, and new techniques for making nano and mesoscopic sensors and detectors.
There is a growing understanding that the progress of the conventional silicon technology will reach its physical, engineering and economic limits in near future. This fact, however, does not mean that progress in computing will slow down. What will take us beyond the silicon era are new nano-technologies that are being pursued in university and corporate laboratories around the world. In particular, molecular switching devices and systems that will self-assemble through molecular recognition are being designed and studied. Many labora tories are now testing new types of these and other reversible switches, as well as fabricating nanowires needed to connect circuit elements together. But there are still significant opportunities and demand for invention and discovery be fore nanoelectronics will become a reality. The actual mechanisms of transport through molecular quantum dots and nanowires are of the highest current ex perimental and theoretical interest. In particular, there is growing evidence that both electron-vibron interactions and electron-electron correlations are impor tant. Further progress requires worldwide efforts of trans-disciplinary teams of physicists, quantum chemists, material and computer scientists, and engineers.

Quickly becoming the hottest topic of the new millennium (2.4 billion dollars funding in US alone) Current status and future trends of micro and nanoelectronics research Written by leading experts in the corresponding research areas Excellent tutorial for graduate students and reference for "gurus" Provides a broad overlook and fundamentals of nanoscience and nanotechnology from chemistry to electronic devices
This book collects papers on the fundamentals and applications of nanoscale devices, first presented at the NATO Advanced Research Workshop on Nanoscale Devices – Fundamentals and Applications held in Kishinev, Moldova, in September 2004. The focus is on the synthesis and characterization of nanoscale magnetic materials; fundamental physics and materials aspects of solid-state nanostructures; development of novel device concepts and design principles for nanoscale devices; and on applications in electronics with emphasis on defence against the threat of terrorism.
Nanotechnology is a 'catch-all' description of activities at the level of atoms and molecules that have applications in the real world. A nanometre is a billionth of a metre, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques. This book presents the latest research in this frontier field.
This book overviews the current status of research and development activities of CNTs in nanodevices, nanomaterials, or nanofabrication. This book presents 15 state-of-the-art review articles that cover CNT synthesis technologies for growing highly orientated CNTs, chirality-pure CNTs and CNTs at a large throughput and low cost, CNT assembly techniques, CNT sorting and separation processes, CNT functionalization engineering for more functionalities, CNT fundamental properties and their practical/potential electrical, electronic, optical, mechanical, chemical and biological applications.
The main intention of the editors of the book is the demonstration of the intrinsic correlation and mutual influence of three important components of nanoscience: new phenomena – nanomaterials – nanodevices. This is the organizing concept of the book. To discover new phenomena it is necessary to develop novel nanotechnological processes for fabrication of nanomaterials. Nanostructures and new phenomena serve as the base for the development of novel nanoelectronic devices and systems. The articles selected for the book illustrate this interrelation.
In this book, internationally recognized researchers give a state-of-the-art overview of the electronic device architectures required for the nano-CMOS era and beyond. Challenges relevant to the scaling of CMOS nanoelectronics are addressed through different core CMOS and memory device options in the first part of the book. The second part reviews new device concepts for nanoelectronics beyond CMOS. The book covers the fundamental limits of core CMOS, improving scaling by the introduction of new materials or processes, new architectures using SOI, multigates and multichannels, and quantum computing.
Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. Many universities, research institutes and companies are working to develop high-Tc superconductivity applications and considerable progress has been made. This volume brings together new leading-edge research in the field.
This book talks about a novel way of arranging the atomic structure of a substance so that it can be made thousands of times stronger than in its native state. It is often used to make duranium a further ten thousand times stronger. Thus, a lump of duranium can be made over ten million times stronger than the equivalent block of titanium. A one dimensional fullerene (a convex cage of atoms with only hexagonal and/ or pentagonal faces) with a cylindrical shape. Carbon nanotubes discovered in 1991 by Sumio Iijima resemble rolled up graphite, although they can not really be made that way. Depending on the direction that the tubes appear to have been rolled (quantified by the 'chiral vector'), they are known to act as conductors or semiconductors. Nanotubes are proving to be useful as molecular components for nanotechnology. This book assembles and presents new and important research in the field.

Implicit Symmetries in Single-Electron Transport Through Real and Artificial Molecules
Author: Konstantin Kikoin
Publisher: Springer Science & Business Media
Category: Technology & Engineering
Group theoretical concepts elucidate fundamental physical phenomena, including excitation spectra of quantum systems and complex geometrical structures such as molecules and crystals. These concepts are extensively covered in numerous textbooks. The aim of the present monograph is to illuminate more subtle aspects featuring group theory for quantum mechanics, that is, the concept of dynamical symmetry. Dynamical symmetry groups complement the conventional groups: their elements induce transitions between states belonging to different representations of the symmetry group of the Hamiltonian. Dynamical symmetry appears as a hidden symmetry in the hydrogen atom and quantum rotator problem, but its main role is manifested in nano and meso systems. Such systems include atomic clusters, large molecules, quantum dots attached to metallic electrodes, etc. They are expected to be the building blocks of future quantum electronic devices and information transmitting algorithms. Elucidation of the electronic properties of such systems is greatly facilitated by applying concepts of dynamical group theory.

In his 1959 address, "There is Plenty of Room at the Bottom," Richard P. Feynman speculated about manipulating materials atom by atom and challenged the technical community "to find ways of manipulating and controlling things on a small scale." This visionary challenge has now become a reality, with recent advances enabling atomistic-level tailoring and control of materials. Exemplifying Feynman’s vision, Handbook of Nanoscience, Engineering, and Technology, Third Edition continues to explore innovative nanoscience, engineering, and technology areas. Along with updating all chapters, this third edition extends the coverage of emerging nano areas even further. Two entirely new sections on energy and biology cover nanomaterials for energy storage devices, photovoltaics, DNA devices and assembly, digital microfluidic lab-on-a-chip, and much more. This edition also includes new chapters on nanomagnet logic, quantum transport at the nanoscale, terahertz emission from Bloch oscillator systems, molecular logic, electronic optics in graphene, and electromagnetic metamaterials. With contributions from top scientists and researchers from around the globe, this color handbook presents a unified, up-to-date account of the most promising technologies and developments in the nano field. It sets the stage for the next revolution of nanoscale manufacturing—where scalable technologies are used to manufacture large numbers of devices with complex functionalities.
