The International Workshop on "Intersubband Transitions in Quantum
Wells:: Physics and Applications," was held at National Cheng Kung
University, in Tainan, Taiwan, December 15-18, 1997. The objective
of the Workshop is to facilitate the presentation and discussion of
the recent results in theoretical, experimental, and applied
aspects of intersubband transitions in quantum wells and dots. The
program followed the tradition initiated at the 1991 conference in
Cargese-France, the 1993 conference in Whistler, B. C. Canada, and
the 1995 conference in Kibbutz Ginosar, Israel. Intersubband
transitions in quantum wells and quantum dots have attracted
considerable attention in recent years, mainly due to the promise
of various applications in the mid- and far-infrared regions (2-30
J. lm). Over 40 invited and contributed papers were presented in
this four-day workshop, with topics covered most aspects of the
intersubband transition phenomena including: the basic intersubband
transition processes, multiquantum well infrared photodetector
(QWIP) physics, large format (640x480) GaAs QWIP (with 9. 0 J. lffi
cutoff) focal plane arrays (FPAs) for IR imaging camera
applications, infrared modulation, intersubband emission including
mid- and long- wavelength quantum cascade (QC) lasers such as short
(A. "" 3. 4 J. lm) and long (A. "" 11. 5 J. lm) wavelength room
temperature QC lasers, quantum fountain intersubband laser at 15. 5
J. lm wavelength in GaAs/AIGaAs quantum well, harmonic generation
and nonlinear effects, ultra-fast phenomena such as terahertz (THz)
intersubband emission and detection. The book divides into five
Chapters.
This work focuses on complementary crystallographic and
spectroscopic areas of dynamic structural science, from papers
presented at the 46th NATO sponsored course in Erice, Sicily 2013.
These papers cover a range of material from background concepts to
more advanced material and represent a fully inter-disciplinary
collection of the latest ideas and results within the field. They
will appeal to practising or novice crystallographers, both
chemical and biological, who wish to learn more about modern
spectroscopic methods and convergent advances and hence vice versa
for experimental and computational spectroscopists.The chapters
refer to the latest techniques, software and results and each
chapter is fully referenced. The volume provides an excellent
starting point for new comers in the emerging, multi-disciplinary
area of time resolved science."
This volume contains review articles which were written by the
invited speak ers of the Sixth International Summer Institute in
Surface Science (ISISS), held at the University of
Wisconsin-Milwaukee in August 1983. The objective of ISISS is to
bring together a group of internationally recognized experts on
various aspects of surface science to present tutorial review
lectures over a period of one week. Each speaker is asked, in addi
tion, to write a review paper on his lecture topic. The collected
articles from previous Institutes have been published under the
following titles: Surface Science: Recent Progress and
Perspectives, Crit. Rev. Solid State Sci. 4, 124-559 (1974).
Chemistry and Physics of Solid Surfaces, Vol. I (1976), Vol. II
(1979), Vol. III (1982) (CRC Press, Boca Raton, FL), and Vol. IV
(1982), Springer Ser. Chern. Phys., Vol. 20 (Springer-Verlag
Berlin, Heidelberg, New York 1982) No single collection of reviews
(or one-week conference for that matter) can possibly cover the
entire field of modern surface science, from heter ogeneous
catalysis through semiconductor surface physics to metallurgy. It
is intended, however, that the series Chemistry and Physics ofSolid
Sur faces as a whole should provide experts and students alike with
a comprehen ve set of reviews and literature references on as many
aspects of the subject as possible, particular emphasis being
placed on the gas-solid interface. Each volume is introduced with a
historical review of the devel opment of one aspect of surface
science by a distinguished participant in that development."

This is the sixth volume of a well-established and popular series
in which expert practitioners discuss topical aspects of light
scattering in solids. This volume discusses recent results of Raman
spectroscopy of high Tc superconductors, organic polymers, rare
earth compounds, semimagnetic superconductors, and silver halides,
as well as developments in the rapidly growing field of
time-resolved Raman spectroscopy. Emphasis is placed on obtaining
information about elementary excitations, the basic properties of
materials, and the use of Raman spectroscopy as an analytical tool.
This volume may be regarded as an encyclopedia of condensed matter
physics from the viewpoint of the Raman spectroscopist. It will be
useful to advanced students and to all researchers who apply Raman
spectroscopy in their work.

In his thesis, Matthias Junk takes an innovative approach to assess
the local structure and dynamics of biological and synthetic
amphiphilic macromolecules capable of transporting small molecules.
Replacing the latter with stable radicals, he uses state-of-the-art
electron paramagnetic resonance (EPR) spectroscopy to describe the
highly relevant transport function from the viewpoint of the guest
molecules. Such, he demonstrates that the functional structure of
human serum albumin in solution significantly differs from its
crystal structure - a consequence of the protein's adaptability to
host various endogenous compounds and drug molecules. Further, he
shows that the thermal collapse of thermoresponsive hydrogels and
dendronized polymers leads to static and dynamic heterogeneities on
the nanoscale. These heterogeneities bear consequences for the
material's hosting properties and enable unforeseen complex
catalytic functionalities.
The "Rudolf Moessbauer Story" recounts the history of the discovery
of the "Moessbauer Effect" in 1958 by Rudolf Moessbauer as a
graduate student of Heinz Maier-Leibnitz for which he received the
Nobel Prize in 1961 when he was 32 years old. The development of
numerous applications of the Moessbauer Effect in many fields of
sciences , such as physics, chemistry, biology and medicine is
reviewed by experts who contributed to this wide spread research.
In 1978 Moessbauer focused his research interest on a new field
"Neutrino Oscillations" and later on the study of the properties of
the neutrinos emitted by the sun.
When I was contacted by Kluwer Academic Publishers in the Fall of
200 I, inviting me to edit a volume of papers on the issue of
electron transport in quantum dots, I was excited by what I saw as
an ideal opportunity to provide an overview of a field of research
that has made significant contributions in recent years, both to
our understanding of fundamental physics, and to the development of
novel nanoelectronic technologies. The need for such a volume
seemed to be made more pressing by the fact that few comprehensive
reviews of this topic have appeared in the literature, in spite of
the vast activity in this area over the course of the last decade
or so. With this motivation, I set out to try to compile a volume
that would fairly reflect the wide range of opinions that has
emerged in the study of electron transport in quantum dots. Indeed,
there has been no effort on my part to ensure any consistency
between the different chapters, since I would prefer that this
volume instead serve as a useful forum for the debate of critical
issues in this still developing field. In this matter, I have been
assisted greatly by the excellent series of articles provided by
the different authors, who are widely recognized as some of the
leaders in this vital area of research.
At present, there is an increasing interest in the prediction of
properties of classical and new materials such as substitutional
alloys, their surfaces, and metallic or semiconductor multilayers.
A detailed understanding based on a thus of the utmost importance
for fu microscopic, parameter-free approach is ture developments in
solid state physics and materials science. The interrela tion
between electronic and structural properties at surfaces plays a
key role for a microscopic understanding of phenomena as diverse as
catalysis, corrosion, chemisorption and crystal growth. Remarkable
progress has been made in the past 10-15 years in the understand
ing of behavior of ideal crystals and their surfaces by relating
their properties to the underlying electronic structure as
determined from the first principles. Similar studies of complex
systems like imperfect surfaces, interfaces, and mul tilayered
structures seem to be accessible by now. Conventional
band-structure methods, however, are of limited use because they
require an excessive number of atoms per elementary cell, and are
not able to account fully for e.g. substitu tional disorder and the
true semiinfinite geometry of surfaces. Such problems can be solved
more appropriately by Green function techniques and multiple
scattering formalism.
Diffusion in solids at moderate temperatures is a well-known
phenomenon. However, direct experimental evidence about the
responsible atomic-scale mechanisms has been scarce, due to
difficulties in probing the relevant length- and time-scales. The
present thesis deals with the application of X-ray Photon
Correlation Spectroscopy (XPCS) for answering such questions. This
is an established method for the study of slow dynamics on
length-scales of a few nanometres. The scattered intensity in the
diffuse regime, i.e. corresponding to atomic distances, is very
low, however, and so it has so far been considered impossible to
use XPCS for this problem. Threefold progress is reported in this
work: It proposes a number of systems selected for high diffuse
intensity, it optimizes the photon detection and data evaluation
procedures, and it establishes theoretical models for
interpretating the results. Together these advances allowed the
first successful atomic-scale XPCS experiment, which elucidated the
role of preferred configurations for atomic jumps in a copper-gold
alloy. The growth in available coherent X-ray intensity together
with next-generation X-ray sources will open up a wide field of
application for this new method.
Photoelectrochemical Hydrogen Production describes the principles
and materials challenges for the conversion of sunlight into
hydrogen through water splitting at a semiconducting electrode.
Readers will find an analysis of the solid state properties and
materials requirements for semiconducting photo-electrodes, a
detailed description of the semiconductor/electrolyte interface, in
addition to the photo-electrochemical (PEC) cell. Experimental
techniques to investigate both materials and PEC device performance
are outlined, followed by an overview of the current
state-of-the-art in PEC materials and devices, and combinatorial
approaches towards the development of new materials. Finally, the
economic and business perspectives of PEC devices are discussed,
and promising future directions indicated. Photoelectrochemical
Hydrogen Production is a one-stop resource for scientists, students
and R&D practitioners starting in this field, providing both
the theoretical background as well as useful practical information
on photoelectrochemical measurement techniques. Experts in the
field benefit from the chapters on current state-of-the-art
materials/devices and future directions.
Monomolecular assemblies on substrates, now termed
Langmuir-Blodgett (LB) films, have been studied for over half a
century. Their development can be viewed in three stages. Following
the pioneering work of Irving Langmuir and Katharine Blodgett in
the late 1930s there was a brief flurry of activity just before and
just after the Second World War. Many years later Hans Kuhn
published his stimulating work on energy transfer. This German
contribution to the field, made in the mid-1960s, can be regarded
as laying the foundation for studies of artificial systems of
cooperat ing molecules on solid substrates. However, the resurgence
of activity in academic and industrial laboratories, which has
resulted in four large international con ferences, would not have
occurred but for British and French groups highlighting the
possible applications of LB films in thefield of electronics. Many
academic and industrial establishments involved in high technology
are now active in or maintaining a watching brief on the field.
Nevertheless this impor tant area of solid state science is still
perhaps largely unfamiliar to many involved in materials or
electronic device research. The richness of the variety of organic
molecular materials suitable for LB film deposition offers enormous
scope for those interested in their basic properties or their
practical applications. LB films are now an integral part of the
field of molecular electronics. It seems inevitable that they will
play some role in replacing inorganic materials in certain areas of
application."
In this book, Yoshimura provides a review of the UHV related
development during the last decades. His very broad experience in
the design enables him to present us this detailed reference. After
a general description how to design UHV systems, he covers all
important issue in detail, like pumps, outgasing, Gauges, and
Electrodes for high voltages. Thus, this book serves as reference
for everybody using UVH in scientific equipment.
Power consumption becomes the most important design goal in a wide
range of electronic systems. There are two driving forces towards
this trend: continuing device scaling and ever increasing demand of
higher computing power. First, device scaling continues to satisfy
Moore's law via a conventional way of scaling (More Moore) and a
new way of exploiting the vertical integration (More than Moore).
Second, mobile and IT convergence requires more computing power on
the silicon chip than ever. Cell phones are now evolving towards
mobile PC. PCs and data centers are becoming commodities in house
and a must in industry. Both supply enabled by device scaling and
demand triggered by the convergence trend realize more computation
on chip (via multi-core, integration of diverse functionalities on
mobile SoCs, etc.) and finally more power consumption incurring
power-related issues and constraints. Energy-Aware System Design:
Algorithms and Architectures provides state-of-the-art ideas for
low power design methods from circuit, architecture to software
level and offers design case studies in three fast growing areas of
mobile storage, biomedical and security. Important topics and
features: - Describes very recent advanced issues and methods for
energy-aware design at each design level from circuit and
architecture to algorithm level, and also covering important blocks
including low power main memory subsystem and on-chip network at
architecture level - Explains efficient power conversion and
delivery which is becoming important as heterogeneous power sources
are adopted for digital and non-digital parts - Investigates 3D die
stacking emphasizing temperature awareness for better perspective
on energy efficiency - Presents three practical energy-aware design
case studies; novel storage device (e.g., solid state disk),
biomedical electronics (e.g., cochlear and retina implants), and
wireless surveillance camera systems. Researchers and engineers in
the field of hardware and software design will find this book an
excellent starting point to catch up with the state-of-the-art
ideas of low power design.
The effects of electromagnetic radiation and high-energy par ticles
on semiconductors can be divided into two main processes: (a) the
excitation of electrons (the special case is internal ioniza tion,
i. e. , the generation of excess charge carriers); and(b) dis
turbance of the periodic structure of the crystal, i. e. , the
forma tion of "structural radiation defects. " Naturally,
investigations of the effects of radiation on semiconductors cannot
be considered in isolation. Thus, for example, the problern of
"radiation de fects" is part of the generalproblern of crystal
lattice defects and the influence of such defects on the processes
occurring in semi conductors. The same is true of photoelectric and
similar phe nomena where the action of the radiation is only the
start of a complex chain of nonequilibrium electronprocesses.
Nevertheless, particularly from the point of view of the
experimental physicist, the radiation effects discussed in the
present book have inter esting features: several types of radiation
may produce the same resul t (for example, ionization by photons
and by charged particles) or one type of radiation may produce
several effects (ionization and radiation -defect formation). The
aim of the author was to consider the most typical prob lems. The
subjects discussed differ widely from one another in the extent to
which they have been investigated.
Proceedings of a NATO ASI held in Les Arcs, France, April 2--13,
1990
The NATO Advanced Research Workshop on Fundamental Aspects of Inert
Gases in Solids, held at Bonas, France from 16-22 September 1990,
was the fifth in a series of meetings that have been held in this
topic area since 1979. The Consultants' Meeting in that year at
Harwell on Rare Gas Behaviour in Metals and Ionic Solids was
followed in 1982 by the Jiilich Inter national Symposium on
Fundamental Aspects of Helium in Metals. Two smaller meetings have
followed-a CECAM organised workshop on Helium Bubbles in Metals was
held at Orsay, France in 1986 while in February 1989, a Topical
Symposium on Noble Gases in Metals was held in Las Vegas as part of
the large TMS/AIME Spring Meeting. As is well known, the dominating
feature of inert gas atoms in most solids is their high heat of
solution, leading in most situations to an essentially zero
solubility and gas-atom precipita tion. In organising the workshop,
one particular aim was to target the researchers in the field of
inert-gas/solid interactions from three different areas--namely
metals, tritides and nuclear fuels-in order to encourage and foster
the cross-fertilisation of approaches and ideas. In these three
material classes, the behaviour of inert gases in metals has
probably been most studied, partly from technological
considerations-the effects of helium production via (n, a) reac
tions during neutron irradiation are of importance, particularly in
a fusion reactor environ ment-and partly from a more fundamental
viewpoint."
