Symmetry and Heterogeneity in High Temperature Superconductors

Product Description

The object of this book is the quantum mechanism that allows the macroscopic quantum coherence of a superconducting condensate to resist to the attacks of high temperature. Solution to this fundamental problem of modern physics is needed for the design of room temperature superconductors, for controlling the decoherence effects in the quantum computers and for the understanding of a possible role of quantum coherence in living matter that is debated today in quantum biophysics. The recent experimental results on nanoscale phase separation and the two component scenario in high T_c in doped cuprate and the lower symmetry in the superconducting elements at high pressure area presented. The compelling evidence for multiband superconductivity in MgB₂ that provides the simplest system for testing the high T_c theories, and plays the same role as atomic hydrogen for the development of the quantum mechanics in the twenties, is one of the main points of the book. The multiband superconductivity enhances the critical temperature from the low T_c range T_c < 19K, to the high temperature range, T_c = 40K. The heterogeneous structure, the superlattice of superconducting layers, determines the disparity and different spatial location of the Bloch wave functions of electrons at the Fermi level that provides in superconductivity the clean limit. The chemical potential can be tuned by atomic substitutions without increasing inelastic single electron interband scattering. The Feshbach shape resonance in the exchange-like off-diagonal interband pairing term, as predicted since 1993, appears to be the mechanism for evading temperature decoherence effects and enhancing the critical temperature.

Nanostructures: Theory and Modelling

Product Description

Progress in nanoscience is becoming increasingly dependent on simulation and modeling. This is due to a combination of three factors: the reduced size of nano-objects, the increasing power of computers, and the development of new theoretical methods. This book represents the first attempt to provide the theoretical background needed by physicists, engineers and students to simulate nano-devices, semiconductor quantum dots and molecular devices. It presents in a unified way the theoretical concepts, the more recent semi-empirical and ab initio methods, and their application to experiments. The topics include quantum confinement, dielectric and optical properties, non-radiative processes, defects and impurities, and quantum transport. This guidebook not only provides newcomers with an accessible overview (requiring only basic knowledge of quantum mechanics and solid-state physics) but also provides active researchers with practical simulation tools.

Nanoelectronics and Information Technology

Product Description
Providing an introduction to electronic materials and device concepts for the major areas of current and future information technology, the value of this book lies in its focus on the underlying principles. Illustrated by contemporary examples, these basic principles will hold, despite the rapid developments in this field, especially emphasizing nanoelectronics.
There is hardly any field where the links between basic
science and application are tighter than in nanoelectronics & information technology. As an example, the design of resonant tunneling transistors, single electron devices or molecular electronic structures is simply inconceivable without delving deep into quantum mechanics.
This textbook is primarily aimed at students of physics,
electrical engineering and information technology, as well as material science in their 3rd year and higher. It is equally of interest to professionals wanting a broader overview of this hot topic.

“Nanoelectronics and Information Technology” by Rainer Waser and his colleagues is an outstanding compendium of
information about an exciting new field. Owing to its high quality and complete coverage of the many topics in this area, this well referenced book will have a long and very useful life as a primary text for students experienced and new in nanoelectronics. It is a very impressive book.” (Richard Siegel)

Quantum Mechanics: An Introduction for Device Physicists and Electrical Engineers, Second Edition

Product Description
This textbook provides a complete course in

quantum mechanics for students of

semiconductor device physics and electrical

engineering. It provides the necessary

background to quantum theory for those starting

work on micro- and nanoelectronic structures and

is particularly useful for those going on to work

with semiconductors and lasers.

This book was developed from a course the

author has taught for many years with a style and

order of presentation of material specifically

designed for this audience. It introduces the main

concepts of quantum mechanics which are

important in everyday solid-state physics and

electronics. Each topic includes examples which

have been carefully chosen to draw upon relevant

experimental research. It also includes problems

with solutions to test understanding of theory. For

the second edition significant new material has

been added to each chapter, providing updated

connections with relevant experiments and device

concepts. New references and new problems are

included.
