The study of high critical temperature superconductors (HTS) is one
of the most prominent research subjects in solid state science. An
understanding of the role of fluctuations is also believed to be
necessary in advance of technological applications, since the
fluctuations may destroy the superconducting state. The discussions
focus on: superconducting fluctuations in the vicinity of the
critical transitions; superconductivity fluctuations near the
percolation transition; and fluctuations of the vortex lattice at
the lattice melting temperature. The effects of fluctuations on
static properties and on electrical and thermal transport,
properties in the ab plane and along the c axis, the effect of a
magnetic field on phenomena, specifically in layered compounds are
still undecided. The effect of a magnetic field is still not clear.
Specific fluctuations of the vortex lattice in HTS ceramics as
compared to conventional superconductors are still intensely
debated.
This book deals with many aspects of high density digital
recording. It begins with very basic concepts in magnetism and
magneto-optics, then continues with the synthesis and physical
properties of recording media, thin films and particulate media.
More technological aspects of recording heads and their contact
with the recording media are also discussed in subsequent chapters.
The second part of the book is devoted to the magneto-optical
properties of various recording media and to the engineering of
magneto-optical recording.
This is the first book to provide a comprehensive treatment of
theories and applications in the rapidly expanding field of the
crystallography of modular materials. Molecules are the natural
modules from which molecular crystalline structures are built. Most
inorganic structures, however, are infinite arrays of atoms and
some kinds of surrogate modules, e.g. co-ordination polyhedra, are
usually used to describe them. In recent years the attention has
been focused on complex modules as the basis for a systematic
description of polytypes and homologous/polysomatic series (modular
structures). This representation is applied to the modelling of
unknown structures and understanding nanoscale defects and
intergrowths in materials. The Order/Disorder (OD) theory is
fundamental to developing a systematic theory of polytypism,
dealing with those structures based on both ordered and disordered
stacking of one or more layers. Twinning at both unit-cell and
micro-scale, together with disorder, causes many problems,
"demons", for computer-based methods of crystal structure
determination. This book develops the theory of twinning with the
inclusion of worked examples, converting the "demons" into useful
indicators for unravelling crystal structure. In spite of the
increasing use of the concepts of modular crystallography for
characterising, understanding and tailoring technological
crystalline materials, this is the first book to offer a unified
treatment of the results, which are spread across many different
journals and original papers published over the last twenty years.
The book provides a technical account of the basic physics of
nanostructures, which are the foundation of the hardware found in
all manner of computers. It will be of interest to semiconductor
physicists and electronic engineers and advanced research students.
Crystalline nanostructures have special properties associated with
electrons and lattice vibrations and their interaction. The result
of spatial confinement of electrons is indicated in the
nomenclature of nanostructures: quantum wells, quantum wires,
quantum dots. Confinement also has a profound effect on lattice
vibrations. The documentation of the confinement of acoustic modes
goes back to Lord Rayleigh's work in the late nineteenth century,
but no such documentation exists for optical modes. It is only
comparatively recently that any theory of the elastic properties of
optical modes exists, and a comprehensive account is given in this
book. A model of the lattice dynamics of the diamond lattice is
given that reveals the quantitative distinction between acoustic
and optical modes and the difference of connection rules that must
apply at an interface. The presence of interfaces in nanostructures
forces the hybridization of longitudinally and transversely
polarized modes, along with, in polar material, electromagnetic
modes. Hybrid acoustic and optical modes are described, with an
emphasis on polar-optical phonons and their interaction with
electrons. Scattering rates in single heterostructures, quantum
wells and quantum wires are described and the anharmonic
interaction in quantum dots discussed. A description is given of
the effects of dynamic screening of hybrid polar modes and the
production of hot phonons.
This book is an introduction to the quantum theory of materials and
first-principles computational materials modelling. It explains how
to use density functional theory as a practical tool for
calculating the properties of materials without using any empirical
parameters. The structural, mechanical, optical, electrical, and
magnetic properties of materials are described within a single
unified conceptual framework, rooted in the Schroedinger equation
of quantum mechanics, and powered by density functional theory.
This book is intended for senior undergraduate and first-year
graduate students in materials science, physics, chemistry, and
engineering who are approaching for the first time the study of
materials at the atomic scale. The inspiring principle of the book
is borrowed from one of the slogans of the Perl programming
language, 'Easy things should be easy and hard things should be
possible'. Following this philosophy, emphasis is placed on the
unifying concepts, and on the frequent use of simple heuristic
arguments to build on one's own intuition. The presentation style
is somewhat cross disciplinary; an attempt is made to seamlessly
combine materials science, quantum mechanics, electrodynamics, and
numerical analysis, without using a compartmentalized approach.
Each chapter is accompanied by an extensive set of references to
the original scientific literature and by exercises where all key
steps and final results are indicated in order to facilitate
learning. This book can be used either as a complement to the
quantum theory of materials, or as a primer in modern techniques of
computational materials modelling using density functional theory.
This book presents developments of techniques for detection and
analysis of two electrons resulting from the interaction of a
single incident electron with a solid surface. Spin dependence in
scattering of spin-polarized electrons from magnetic and
non-magnetic surfaces is governed by exchange and spin-orbit
effects. The effects of spin and angular electron momentum are
shown through symmetry of experimental geometries: (i) normal and
off normal electron incidence on a crystal surface, (ii) spin
polarization directions within mirror planes of the surface, and
(iii) rotation and interchange of detectors with respect to the
surface normal. Symmetry considerations establish relationships
between the spin asymmetry of two-electron distributions and the
spin asymmetry of Spectral Density Function of the sample, hence
providing information on the spin-dependent sample electronic
structure. Detailed energy and angular distributions of electron
pairs carry information on the electron-electron interaction and
electron correlation inside the solid. The "exchange - correlation
hole" associated with Coulomb and exchange electron correlation in
solids can be visualized using spin-polarized two-electron
spectroscopy. Also spin entanglement of electron pairs can be
probed. A description of correlated electron pairs generation from
surfaces using other types of incident particles, such as photons,
ions, positrons is also presented.
This book describes available tribology technologies and introdces
a comprehensive overview of tribology. General, up-to-date
knowledge on how tribology is approached in various related areas
of research, both experimental and computational is provided.
During the last thirty years metal surface physics, or generally
surface science, has come a long way due to the development of
vacuum technology and the new surface sensitive probes on the
experimental side and new methods and powerful computational
techniques on the theoretical side. The aim of this book is to
introduce the reader to the essential theoretical aspects of the
atomic and electronic structure of metal surfaces and interfaces.
The book gives some theoretical background to students of
experimental and theoretical physics to allow further exploration
into research in metal surface physics.
The book consists of three parts. The first part is devoted to
classical description of geometry and structure of metal crystals
and their surfaces and surface thermodynamics including properties
of small metallic particles. Part two deals with quantum-mechanical
description of electronic properties of simple metals. It starts
from the free electron gas description and introduces the many body
effects in the framework of the density functional theory, in order
to discuss the basic surface electronic properties of simple
metals. This part outlines also properties of alloy surfaces, the
quantum size effect and small metal clusters. Part three gives a
succinct description of metal surfaces in contact with foreign
atoms and surfaces. It treats the work function changes due to
alkali metal adsorption on metals, adhesion between metals and
discusses the universal aspects of the binding energy curves. In
each case extensive reference lists are provided.
Since its inception in 1966, the series of numbered volumes known
as Semiconductors and Semimetals has distinguished itself through
the careful selection of well-known authors, editors, and
contributors. The "Willardson and Beer" Series, as it is widely
known, has succeeded in publishing numerous landmark volumes and
chapters. Not only did many of these volumes make an impact at the
time of their publication, but they continue to be well-cited years
after their original release. Recently, Professor Eicke R. Weber of
the University of California at Berkeley joined as a co-editor of
the series. Professor Weber, a well-known expert in the field of
semiconductor materials, will further contribute to continuing the
series' tradition of publishing timely, highly relevant, and
long-impacting volumes. Some of the recent volumes, such as
Hydrogen in Semiconductors, Imperfections in III/V Materials,
Epitaxial Microstructures, High-Speed Heterostructure Devices,
Oxygen in Silicon, and others promise that this tradition will be
maintained and even expanded.
Reflecting the truly interdisciplinary nature of the field that the
series covers, the volumes in Semiconductors and Semimetals have
been and will continue to be of great interest to physicists,
chemists, materials scientists, and device engineers in modern
industry.

Solid State Physics, Volume 71 provides the latest volume in this
long-running series. This latest volume highlights new advances in
the field, with this new volume presenting interesting chapters
written by an international board of authors.
This volume contains a selection of important papers by P.G. de
Gennes (1991 Nobel Prize Winner in Physics) which have had a
long-lasting impact on the understanding of condensed matter (solid
state physics, liquid crystals, polymers, interfaces, wetting and
adhesion). A typical example is the original article on "reptation"
of polymer chains. The author has added some "afterthoughts" to the
main papers (explaining their successes or weaknesses), and some
current views on each special problem. Complex systems (polymers or
granular matters, and so forth) are explained without heavy
calculations, using simple scaling laws as the main tool.
Magnetic impurities in a non-magnetic host metal have been actively
explored in condensed matter physics in recent last decades. From
both fundamental and applied viewpoints these systems are very
interesting because they can exhibit strong electronic correlations
that give rise to various fascinating phenomena beyond the single
particle picture. Up to now our understanding of the underlying
processes remains limited due to difficulties involved in measuring
these systems on a microscopic scale. With their unique control,
scanning tunneling microscopy (STM) and spectroscopy (STS) allow
for the first time investigations of phenomena occurring on very
small length and energy scales. Here, single magnetic iron and
cobalt atoms embedded beneath a metal surface are investigated
using these techniques. In particular, the transition from single
impurity Kondo physics to two interacting impurities is studied in
real space. This thesis contains a comprehensive description of the
STM /STS technique, sub-surface impurities, as well as single- and
two-impurity Kondo physics - and as such offers a valuable
introduction to newcomers to the field.
This book provides a comprehensive overview of the photonic sensing
field by covering plasmonics, photonic crystal, and SOI techniques
from theory to real sensing applications. A literature review of
ultra-sensitive photonic sensors, including their design and
application in industry, makes this a self-contained and
comprehensive resource for different types of sensors, with high
value to the biosensor sector in particular. The book is organized
into four parts: Part I covers the basic theory of wave
propagation, basic principles of sensing, surface plasmon
resonance, and silicon photonics; Part II details the computational
modeling techniques for the analysis and prediction of photonic
sensors; Part III and Part IV cover the various mechanisms and
light matter interaction scenarios behind the design of photonic
sensors including photonic crystal fiber sensors and SOI sensors.
This book is appropriate for academics and researchers specializing
in photonic sensors; graduate students in the early and
intermediate stages working in the areas of photonics, sensors,
biophysics, and biomedical engineering; and to biomedical,
environmental, and chemical engineers.
This book provides a pedagogical introduction to the concepts and
methods of quantum field theory necessary for the study of
condensed matter and ultracold atomic gases. After a thorough
discussion of the basic methods of field theory and many-body
physics (functional integrals, perturbation theory, Feynman
diagrams, correlation functions and linear response theory,
symmetries and their consequences, etc.), the book covers a wide
range of topics, from electron gas and Fermi-liquid theory to
superfluidity and superconductivity, magnetic instabilities in
electron systems, and dynamical mean-field theory of Mott
transition. The focus is on the study of model Hamiltonians, where
the microscopic physics and characteristic energy scales are
encoded into a few effective parameters, rather than
first-principle methods which start from a realistic Hamiltonian at
the microscopic level and then make material-specific predictions.
The reader is expected to be familiar with elementary quantum
mechanics and statistical physics, and some acquaintance with
condensed-matter physics and ultracold gases may also be useful. No
prior knowledge of field theory or many-body problem is required.

This book is a monograph on chaos in dissipative systems written
for those working in the physical sciences. Emphasis is on symbolic
description of the dynamics and various characteristics of the
attractors, and written from the view-point of practical
applications without going into formal mathematical rigour. The
author used elementary mathematics and calculus, and relied on
physical intuition whenever possible. Substantial attention is paid
to numerical techniques in the study of chaos. Part of the book is
based on the publications of Chinese researchers, including those
of the author's collaborators.
This book presents the findings of experimental and theoretical
(including first-principles molecular dynamics simulation) studies
of nanostructured and nanocomposite metal-based materials, and
nanoscale multilayer coatings fabricated by physical or chemical
vapor deposition, magnetron sputtering, electrospark alloying,
ionic layer absorption, contact melting, and high-current electron
beam irradiation. It also discusses novel methods of nanocomposite
formation, as well as the structure of the deposited films,
coatings and other nanoscale materials, their elemental and phase
composition, and their physical-mechanical, tribological, magnetic
and electrical properties. Lastly, it explores the influence of a
various surface modification methods, such as thermal annealing,
pulsed laser modification, and thermomechanical and ultrasonic
treatment, as well as different properties of nanostructured films.
This thesis focuses on the study of the optical response of new
atomically thin two-dimensional crystals, principally the family of
transition metal dichalcogenides like MoS2. One central theme of
the thesis is the precise treatment of the linear and second-order
nonlinear optical susceptibilities of atomically thin transition
metal dichalcogenides. In addition to their significant scientific
interest as fundamental material responses, these studies provide
essential knowledge and convenient characterization tools for the
application of these 2D materials in opto-electronic devices.
Another important theme of the thesis is the valley physics of
atomically thin transition metal dichalcogenides. It is shown that
the degeneracy in the valley degree of freedom can be lifted and a
valley polarization can be created using a magnetic field, which
breaks time reversal symmetry in these materials. These findings
enhance our basic understanding of the valley electronic states and
open up new opportunities for valleytronic applications using
two-dimensional materials.
In recent years, there have been important developments in the
design and fabrication of new thermoelectrics. While a decade ago,
progress was mainly empirical, recent advances in theoretical
methods have led to a deeper understanding of the parameters that
affect the performance of materials in thermoelectric devices.
These have brought the goal of producing materials with the
required characteristics for commercial application a significant
step closer. A search for efficient materials requires a fully
microscopic treatment of the charge and heat transport, and the aim
of this book is to explain all thermoelectric phenomena from this
modern quantum-mechanical perspective. In the first part on
phenomenology, conjugate current densities and forces are derived
from the condition that the rate of change of the entropy density
of the system in the steady state is given by the scalar product
between them. The corresponding transport coefficients are
explicitly shown to satisfy Onsager's reciprocal relations. The
transport equations are solved for a number of cases, and the
coefficient of performance, the efficiency, and the figure of merit
are computed. State-of-the-art methods for the solution of the
transport equations in inhomogeneous thermoelectrics are presented.
A brief account on how to include magnetization transport in the
formalism is also given. In the second part, quantum mechanical
expressions for the transport coefficients are derived, following
the approach by Luttinger. These are shown to satisfy Onsager's
relations by construction. Three lattice models, currently used to
describe strongly correlated electron systems, are introduced: the
Hubbard, the Falicov-Kimball, and the periodic Anderson model
(PAM), and the relevant current density operators are derived for
each of them. A proof of the Jonson-Mahan theorem, according to
which all transport coefficients for these models can be obtained
from the integral of a unique transport function multiplied by
different powers of the frequency, is given. The third part
compares theory and experiment. First for the thermoelectric
properties of dilute magnetic alloys, where the theoretical results
are obtained from poor man's scaling solutions to single impurity
models. Then it is shown that the experimental data on heavy
fermions and valence fluctuators are well reproduced by the
transport coefficients computed for the PAM at low and high
temperature. Finally, results obtained from first principles
calculations are shown, after a short introduction to density
functional theory and beyond. A number of useful appendices
complete the book.
This book gathers together comprehensive information which test and
process professionals will find invaluable. The techniques outlined
will help ensure that test methods and data collected reflect
actual device performance, rather than 'testing the tester' or
being lost in the noise floor.
This book addresses the fundamental issues underlying the
semiconductor test discipline. The test engineer must understand
the basic principles of semiconductor fabrication and process and
have an in-depth knowledge of circuit functions, instrumentation
and noise sources.
Introduces a novel component-testing philosophy for semiconductor
test, product and design engineers.
Best new source of information for experienced semiconductor
engineers as well as entry-level personnel.
Eight chapters about semiconductor testing.
This book provides a comprehensive overview of the science of
nanostructured oxides. It details the fundamental techniques and
methodologies involved in oxides thin film and bulk growth,
characterization and device processing, as well as
heterostructures. Both, experts in oxide nanostructures and experts
in thin film heteroepitaxy, contribute the interactions described
within this book.
These proceedings comprise invited and contributed papers presented
at PLMMP-2014, addressing modern problems in the fields of liquids,
solutions and confined systems, critical phenomena, as well as
colloidal and biological systems. The book focuses on
state-of-the-art developments in contemporary physics of liquid
matter. The papers presented here are organized into four parts:
(i) structure of liquids in confined systems, (ii) phase
transitions, supercritical liquids and glasses, (iii) colloids, and
(iv) medical and biological aspects and cover the most recent
developments in the broader field of liquid state including
interdisciplinary problems.
