Chemical Sensing with Solid State Devices


Book Description

This book is a lucid presentation for chemists, electrical engineers, surface scientists, and solid-state physicists, of the fundamentals underlying the construction of simple and small chemical sensors. The first part of the book is a review of the theoretical background in solid state physics, chemistry and electronics. Semiconductor and solid electrolyte bulk models are reviewed as well as solid/gas and solid/liquid interface models. Membranes and catalysis theory are also covered expansively. The second part is a discussion of more complete sensor devices, their essential components, and of the important developments in this area over the last fifteen to twenty years. The book provides guidance through the multidisciplinary world of chemical sensors. It should be understandable to students with some training in physics and chemistry and a general knowledge of electronics. Finally, comments on economic considerations in the development of new sensor products and suggestionsfor future research and development should be of value to company R&D planners.




Solid State Chemical Sensors


Book Description

Solid State Chemical Sensors reviews the basic chemical and physical principles involved in the construction and operation of solid state sensors. A major portion of the book is devoted to explanation of the basic mechanism of operation and the many actual and potential applications of field effect transistors for gas and solution sensing. This text is comprised of four chapters; the first of which describes the basics of device fabrication. Emphasis is placed on the physical description of semiconductor devices with catalytic metal gates, along with their drawbacks and their promise. The behavior of hydrogen in the Pd-SiO2 system is also considered, and some applications of hydrogen-sensitive transistors, such as smoke detection and biochemical reaction monitoring, are described. The second chapter focuses on chemically sensitive field effect transistors and their thermodynamics, while the third chapter explains the general fabrication procedure for solid state chemical sensors. The final chapter introduces the reader to piezoelectric and pyroelectric chemical sensors, paying particular attention to the sensor nature of piezoelectricity, the piezoelectric gravimetric sensor, and pyroelectric gas analysis. This book is intended to assist electrical engineers in understanding the chemistry involved in the construction and operation of solid state sensors and to educate chemists in solid state science.




Physics, Chemistry and Technology of Solid State Gas Sensor Devices


Book Description

Research and development of solid state gas sensor devices began in the 1950s with several uncoordinated independent efforts. The number and pace of these investigations later accelerated in response to increasing pressure placed on the environment and public health by industrial activities. Since 1970, several thousand articles have been written on the subject, and laboratories around the globe have introduced novel methodologies and devices to address needs associated with particular technological developments. Despite the rapid development of this important new technology, very little has been done to review and coordinate data related to sensor science and technology itself. Physics, Chemistry and Technology of Solid State Gas Sensor Devices focuses on the underlying principles of solid state sensor operation and reveals the rich fabric of interdisciplinary science that governs modern sensing devices. Beginning with some historical and scientific background, the text proceeds to a study of the interactions of gases with surfaces. Subsequent chapters present detailed information on the fabrication, performance, and application of a variety of sensors. Types of sensor devices discussed include: Gas-sensitive solid state semiconductor sensors Photonic and photoacoustic gas sensors Fiber optic sensors Piezoelectric quartz crystal microbalance sensors Surface acoustic wave sensors Pyroelectric and thermal sensors For analytical chemists using solid state sensors in environment-related analysis, and for electrical engineers working with solid state sensors, this book will expand and unify their understanding of these devices, both in theory and practice.

Principles of Chemical Sensors


Book Description

Do not learn the tricks of the trade, learn the trade I started teachinggraduate coursesin chemical sensors in early 1980s, ?rst as a o- quarter (30 h) class then as a semester course and also as several intensive, 4–5-day courses. Later I organized my lecture notes into the ?rst edition of this book, which was published by Plenum in 1989 under the title Principles of Chemical Sensors. I started working on the second edition in 2006. The new edition of Principles of Chemical Sensors is a teaching book, not a textbook. Let me explain the difference. Textbooks usually cover some more or less narrow subject in maximum depth. Such an approach is not possible here. The subject of chemical sensors is much too broad, spanning many aspects of physical and analytical chemistry, biochemistry, materials science, solid-state physics, optics, device fabrication, electrical engine- ing, statistical analysis, and so on. The challengefor me has been to present uniform logical coverage of such a large area. In spite of its relatively shallow depth, it is intended as a graduate course. At its present state the amount of material is more thancan be coveredin a one-semestercourse (45h). Two one-quartercourseswould be more appropriate. Because of the breadth of the material, the sensor course has a somewhat unexpected but, it is hoped, bene?cial effect.




Chemical Sensor Technology


Book Description

Chemical Sensor Technology is a series of annual reviews reporting the latest progress being made in research and technology, both basic and applied, regarding chemical sensors. Chemical sensors continue to grow rapidly in importance encompassing a broad spectrum of technologies covering safety, pollution, fuel economy, medical engineering and industrial processes. Various types of chemical sensors have been devised for detection and monitoring of chemical substances in gases, solutions and organisms, and much work is being done to produce sensitive, selective, reliable and inexpensive sensors. The series aims at contributing to the progress of research and development of chemical sensors. Contributors to the individual volumes are carefully selected by an international editorial board who ensure that as many innovative studies as possible are included. Each article describes a specific topic and is the original work of an expert working in the front lines of chemical sensor research. Contributors are encouraged to describe not only the academic or technological essence of the subject, but also the background and philosophy, evaluation and achievements and future problems. In this way, each topic is described in sufficient depth so as to be useful and stimulating to readers.

Gas Sensors


Book Description

There were two reasons that induced me to plan and to organize this book, the first was the lack of a text entirely devoted to the subject of gas sensors, notwithstanding some books devoted to the various kind of chemical sensors have recently been published. The second reason was the need of introducing the basic topics of gas detection mechanisms to a growing number of researchers active in research and development laboratories of industries and uni versities. The field of chemical sensors is indeed in fast and consistent growth, as it is proved by the increased number of participants to the congresses that were recently held on this subject, namely the Third Meeting on Chemical Sensors (September 24 - 26, 1990, Cleveland), Transducers' 91 (June 24 - 27, 1991, S. Francisco) and EUROSENSORS V (September 30 - October 3, 1991, Rome). Therefore, this book is mainly intended as a reference text for researchers with a MS degree in physics, chemistry and electrical engineering; it reports the last progresses in the R. & D. and in the technology of gas sensors. I choose to deal specifically with the topic of gas sensors because these devices show a very large number of applications in the domestic and industrial field and they are characterized by a great effort of research and development.
