The major thrust of this book is the realisation of an all optical
computer. To that end it discusses optoelectronic devices and
applications, transmission systems, integrated optoelectronic
systems and, of course, all optical computers. The chapters on
heterostructure light emitting devices' quantum well carrier
transport optoelectronic devices' present the most recent advances
in device physics, together with modern devices and their
applications. The chapter on microcavity lasers' is essential to
the discussion of present and future developments in solid-state
laser physics and technology and puts into perspective the present
state of research into and the technology of optoelectronic
devices, within the context of their use in advanced systems. A
significant part of the book deals with problems of propagation in
quantum structures. soliton-based switching, gating and
transmission systems' presents the basics of controlling the
propagation of photons in solids and the use of this control in
devices. The chapters on optoelectronic processing using smart
pixels' and all optical computers' are preceded by introductory
material in fundamentals of quantum structures for optoelectronic
devices and systems' and linear and nonlinear absorption and
reflection in quantum well structures'. It is clear that new
architectures will be necessary if we are to fully utilise the
potentiality of electrooptic devices in computing, but even current
architectures and structures demonstrate the feasibility of the all
optical computer: one that is possible today.
A recent major development in high technology, and one which bears
considerable industrial potential, is the advent of low-dimensional
semiconductor quantum structures. The research and development
activity in this field is moving fast and it is thus important to
afford scientists and engineers the opportunity to get updated by
the best experts in the field. The present book draws together the
latest developments in the fabrication technology of quantum
structures, as well as a competent and extensive review of their
fundamental properties and some remarkable applications. The book
is based on a set of lectures that introduce different aspects of
the basic knowledge available, it has a tutorial content and could
be used as a textbook. Each aspect is reviewed, from elementary
concepts up to the latest developments. Audience: Undergraduates
and graduates in electrical engineering and physics schools. Also

This Advanced Study Institute on the topic of SOLID STATE
MICROBATTERIES is the third and final institute on the general
theme of a field of study now termed "SOLID STATE IONICS". The
institute was held in Erice, Sicily, Italy, 3 - 15 July 1988. The
objective was to assemble in one location individuals from industry
and academia expert in the fields of microelectronics and solid
state ionics to determine the feasibility of merging a solid state
microbattery with microelectronic memory. Solid electrolytes are in
principle amenable to vapor deposition, RF or DC sputtering, and
other techniques used to fabricate microelectronic components. A
solid state microbattery 1 1 mated on the same chip carrier as the
chip can provide on board memory backup power. A solid state
microbattery assembled from properly selected anode/solid
electrolyte/cathode materials could have environmental endurance
properties equal or superior to semiconductor memory chips.
Lectures covering microelectronics, present state-of-art solid
state batteries, new solid electrolyte cathode materials,
theoretical and practical techniques for fabrication of new solid
electrolytes, and analytical techniques for study of solid
electrolytes were covered. Several areas where effort is required
for further understanding of materials in pure form and their
interactions with other materials at interfacial contact points
were identified. Cathode materials for solid state batteries is one
particular research area which requires attention. Another is a
microscopic model of conduction in vitreous solid electrolytes to
enhance the thermodynamic macroscopic Weak ~lectrolyte Iheory
(WET).
Low-dimensional semiconductor quantum structures are a major,
high-technological development that has a considerable industrial
potential. The field is developing extremely rapidly and the
present book represents a timely guide to the latest developments
in device technology, fundamental properties, and some remarkable
applications. The content is largely tutorial, and the book could
be used as a textbook. The book deals with the physics,
fabrication, characteristics and performance of devices based on
low-dimensional semiconductor structures. It opens with fabrication
procedures. The fundamentals of quantum structures and
electro-optical devices are dealt with extensively. Nonlinear
optical devices are discussed from the point of view of physics and
applications of exciton saturation in MQW structures.
Waveguide-based devices are also described in terms of linear and
nonlinear coupling. The basics of pseudomorphic HEMT technology,
device physics and materials layer design are presented. Each
aspect is reviewed from the elementary basics up to the latest
developments. Audience: Undergraduates in electrical engineering,
graduates in physics and engineering schools. Useful for active
scientists and engineers wishing to update their knowledge and

Semimagnetic semiconductors (SMSC) and diluted magnetic
semiconductors (DMS) have in the past decade attracted considerable
attention because they confer many new physical properties on both
bulk materials and heterostructures. These new effects are due
either to exchange interactions between magnetic moments on
magnetic ions, or to exchange interactions between magnetic moments
and the spin of the charge carrier. These effects vary with the
transition metal (Mn, Fe, Co) or rare earth (Eu, Gd, etc) used and
thus provide a range of different situations. The field is very
large (zero gap, small gap, wide gap), and the magnetic properties
also are very rich (paramagnetic spin glass, antiferromagnetism).
These materials are very convenient for studying the magnetism (the
magnetism is diluted) or the superlattices (SL) with a continuous
change from type II SL to type III SL. This Course attempted to
provide a complete overview of the topic. The participants of this
summer school held in Erice came from ten countries and were from
various backgrounds and included theoreticians, experimentalists,
physicists, and chemists. Consequently, an attempt was made to make
the Course as thorough as possible, but at the same time attention
was devoted to basic principles. The lecturers, drawn from all the
groups in the world involved in the field, were asked to be very
didactic in their presentation. After two introductory lectures,

The rediscovery of fast ion conduction in solids in the 1960's
stimulated interest both in the scientific community in which the
fundamentals of diffusion, order-disorder phenomena and crystal
structure evaluation required re-examination, and in the technical
community in which novel approaches to energy conversion and
chemical sensing became possible with the introduction of the new
field of "Solid State Ionics. " Because of both the novelty and the
vitality of this field, it has grown rapidly in many directions.
This growth has included the discovery of many new crystalline fast
ion conductors, and the extension to the fields of organic and
amorphous compounds. The growth has involved the extension of
classical diffusion theory in an attempt to account for carrier
interactions and the development of sophisticated computer models.
Diffraction techniques have been refined to detect carrier
distributions and anharmonic vibrations. Similar advances in the
application of other techniques such as NMR, Raman, IR, and
Impedance Spectroscopies to this field have also occurred. The
applications of fast ion conducting solid electrolytes have also
developed in many directions. High energy density Na/S batteries
are now reaching the last stages of development, Li batteries are
being implanted in humans for heart pacemakers, and solid state
fuel cells are again being considered for future power plants. The
proliferation of inexpensive microcomputers has stimulated the need
for improved chemical sensors--a major application now being the
zirconia auto exhaust sensor being sold by the millions each year.

the two major fields: Electro-Optical Devices and Pseudomorphic
High Eectron Mobility Transistors are extensively discussed."
This textbook combines a thorough theoretical treatment of the
basic physics of semiconductors with applications to practical
devices by putting special emphasis on the physical principles upon
which these devices operate. Topics treated are the detailed band
structure of semiconductors, the effect of impurities on electronic
states, and semiconductor statistics. Also discussed are lattice
dynamical, transport, and surface properties as well as optical,
magneto-optical, and electro-optical properties. The applied part
of the book treats p-n junctions, bipolar junction transistors,
semiconductor lasers and photodevices, after which the subject of
heterostructures and superlattices is taken up with coverage of
electronic, lattice dynamical, optical, and transport properties.
The book concludes with treatments of metal-semiconductor devices
such as MOSFETs and devices based on heterostructures. Graduate
students and lecturers in semiconductor physics, condensed matter
physics, electromagnetic theory, and quantum mechanics will find
