From the Author's Preface
Ceramic sensors have been in use for more than thirty years. Since ceramics exhibit a number of specific characteristics that enable their cost to become lower and their reliability to increase, they have occupied a significant position in sensor technology. This is why many companies and universities have directed their efforts towards investigating and developing new ceramic sensors and expanding their areas of application.
To the best of our knowledge.., there has been] no book treating different sensors on the basis of their common physical and chemical properties, technological principles, and applications. This book is] a detailed survey of ceramic sensors and a generalization of the results achieved in this field so far. Ceramic sensors for different physical quantities are discussed without going too deep into theory...
The concept of ceramic sensors includes all sensors that are produced using ceramic technology. It also covers thick film sensors, since from a structural and technological point of view, they can be regarded as a variety of ceramic sensors. The subject of scientific research in this book is humidity, gas. temperature, and pressure sensors on the basis of semiconductor and dielectric ceramic materials and solid electrolytes.
Special attention is paid to the physical and chemical, as well as the technological, bases of ceramic sensors, their classification, the types of materials used..., the methods of controlling their parameters and characteristics, the areas of application, and the electric circuits for connecting the sensors.

We live in a time of great change. In the electronics world, the last several decades have seen unprecedented growth and advancement, described by Moore's law. This observation stated that transistor density in integrated circuits doubles every 1. 5-2 years. This came with the simultaneous improvement of individual device perf- mance as well as the reduction of device power such that the total power of the resulting ICs remained under control. No trend remains constant forever, and this is unfortunately the case with Moore's law. The trouble began a number of years ago when CMOS devices were no longer able to proceed along the classical scaling trends. Key device parameters such as gate oxide thickness were simply no longer able to scale. As a result, device o- state currents began to creep up at an alarming rate. These continuing problems with classical scaling have led to a leveling off of IC clock speeds to the range of several GHz. Of course, chips can be clocked higher but the thermal issues become unmanageable. This has led to the recent trend toward microprocessors with mul- ple cores, each running at a few GHz at the most. The goal is to continue improving performance via parallelism by adding more and more cores instead of increasing speed. The challenge here is to ensure that general purpose codes can be ef?ciently parallelized. There is another potential solution to the problem of how to improve CMOS technology performance: three-dimensional integrated circuits (3D ICs).

R4,452 Discovery Miles 44 520 Ships in 10 - 15 working days

Interfaces between dissimilar materials are met everywhere in microelectronics and microsystems. In order to ensure faultless operation of these highly sophisticated structures, it is mandatory to have fundamental understanding of materials and their interactions in the system. In this difficult task, the traditional method of trial and error is not feasible anymore; it takes too much time and repeated efforts. In "Interfacial Compatibility in Microelectronics," an alternative approach is introduced.

In this revised method four fundamental disciplines are combined: i) thermodynamics of materials ii) reaction kinetics iii) theory of microstructures and iv) stress and strain analysis. The advantages of the method are illustrated in "Interfacial Compatibility in Microelectronics" which includes:

solutions to several common reliability issues in microsystem technology,

methods to understand and predict failure mechanisms at interfaces between dissimilar materials and

an approach to DFR based on deep understanding in materials science, rather than on the use of mechanistic tools, such as FMEA.

Interfacial Compatibility in Microelectronics provides a clear and methodical resource for graduates and postgraduates alike."

R3,370 Discovery Miles 33 700 Ships in 12 - 17 working days

The application of molecules in technological devices hinges on the proper understanding of their behavior on metallic electrodes or substrates. The intrinsic molecular electronic and magnetic properties are modified at a metallic interface, and greatly depend on the atomic configuration of the molecule-metal bond. This poses certain problems, such as the lack of reproducibility in the transport properties of molecular junctions, but also offers the possibility to induce new charge and spin configurations that are only present at the interface. The results presented in this thesis address this issue, providing a comprehensive overview of the influence of molecule-metal and molecule-molecule interactions on the electronic and magnetic properties of molecules adsorbed on metallic substrates. Using metal-phthalocyanines (MePc), a commonly used metal-organic complex as a model system, each chapter explores different aspects of the interaction with silver surfaces: the local adsorption geometry, self-assembly, the modifications of the electronic and magnetic characteristics due to hybridization and charge transfer, and finally the manipulation of molecular charge and spin states by electron doping using alkali atoms moved with the STM tip.

This book examines both the potential application of electronic nose technology, and the current state of development of chemical sensors for the detection of vapours from explosives, such as those used in landmines. The two fields have developed, somewhat in parallel, over the past decade and so one of the purposes of this workshop, on which the book is based, was to bring together scientists from the two fields in order to challenge the two communities and, mutually, stimulate both fields.

It begins with a review of the basic principles of an electronic nose and explores possible ways in which the detection limit of conventional electronic nose technology can be reduced to the level required for the trace levels observed for many explosive materials. Next are reviews of the use of several different types of solid-state chemical sensors: polymer-based sensors, i.e. chemiluminescent, fluorescent and optical, to detect explosive materials; metal oxide semiconducting resistive sensors; and then electrochemical sensors. Next, different pattern recognition techniques are presented to enhance the performance of chemical sensors. Then biological systems are considered as a possible blue-print for chemical sensing. The biology can be employed either to understand the way insects locate odorant sources, or to understand the signal processing neural pathways. Next is a discussion of some of the new types of electronic noses; namely, a fast GC column with a SAW detector and a micromechanical sensor. Finally, the important issues of sampling technologies and the design of the microfluidic systems are considered. In particular, the use of pre-concentrators and solid phase micro extractors to boost the vapour concentration before it is introduced to the chemical sensor or electronic nose.

This book is loosely based on a Multidisciplinary University Research Initiative (MURI) project and a few supplemental projects sponsored by the Of?ce of Naval Research (ONR) during the time frame of 2004-2009. The initial technical scope and vision of the MURI project was formulated by Drs. Larry Cooper and Joel Davis, both program of?cers at ONR at the time. The unifying theme of this MURI project and its companionefforts is the concept of cellular nonlinear/neuralnetwork (CNN) technology and its various extensions and chip implementations, including nanoscale sensors and the broadening ?eld of cellular wave computing. In recent years, CNN-based vision system drew much attention from vision scientists to device technologists and computer architects. Due to its early - plementation in a two-dimensional (2D) topography, it found success in early vision technologyapplications, such as focal-plane arrays, locally adaptable sensor/ processor integration, resulting in extremely high frame rates of 10,000 frames per second. More recently it drew increasing attention from computer architects, due to its intrinsic local interconnect architecture and parallel processing paradigm. As a result, a few spin-off companies have already been successful in bringing cel- lar wave computing and CNN technology to the market. This book aims to capture some of the recent advances in the ?eld of CNN research and a few select areas of applications.

The morphology that results during the growth of a material on the substrate of a different material is central to the fabrication of all quantum heterostructures. This morphology is determined by several factors, including the manner in which strain is accommodated if the materials have different lattice constants. One of the most topical manifestations of lattice mis't is the formation of coherent thr- dimensional(3D)islandsduringtheStranski-Krastanovgrowthofahighly-strained system. The prototypical cases are InAs on GaAs(001) and Ge on Si(001), though other materials combinations also exhibit this phenomenon. When the 3D islands are embedded within epitaxiallayers of a material that has a wider band gap, the carriers within the islands are con?ned by the potential barriers that surround each island, forming an array of quantum dots (QDs). Such structures have been produced for both basic physics studies and device fab- cation, including QD lasers and light-emitting diodes (LEDs) operating at the c- mercially important wavelengths of 1.3 u m and 1.55 u m. On a more speculative level, QD ensembles have been suggested as a possible pathway for the solid-state implementation of a quantum computer. Although some of the principles of qu- tum computing have been veri?ed by other means, the practical utilization of this new computingparadigmmay warrant some sort of solid state architecture. QDs are seen as possible components of such a computer, as evidenced by a number of papersappearingintheliteratureproposingQD-basedarchitecturesandworkshops that are being organized to explore these possibilities."
