Book excerpt: The development is described of a laboratory model oxygen partial pressure sensor using a sputtered zinc oxide thin film. The film is operated at about 400 C through the use of a miniature silicon bar. Because of the unique resistance versus temperature relation of the silicon bar, control of the operational temperature is achieved by controlling the resistance. A circuit for accomplishing this is described. The response of sputtered zinc oxide films of various thicknesses to oxygen, nitrogen, argon, carbon dioxide, and water vapor caused a change in the film resistance. Over a large range, film conductance varied approximately as the square root of the oxygen partial pressure. The presence of water vapor in the gas stream caused a shift in the film conductance at a given oxygen partial pressure. A theoretical model is presented to explain the characteristic features of the zinc oxide response to oxygen.

Available in PDF, EPUB and Kindle. Book excerpt: Gas Sensors Based on Conducting Metal Oxides: Basic Understanding, Technology and Applications focuses on two distinct types of gas sensors based on conducting metal oxides. Ion conduction, applied in so-called solid-state electrolytic sensors for one, and electronic conduction used in semiconductivity gas sensors for the other. The well-known ?–probe, a key component to optimize combustion in car engines, is an example of the former type, and the in-cabin car air-quality control SnO2 and WO2 sensor array stands for the semiconductivity type. Chapters cover basic aspects of functioning principles and describe the technologies and challenges of present and future sensors. - Provides reader background and context on sensors, principles, fabrication and applications - Includes chapters on specific technological applications, such as exhaust sensors, environmental sensors, explosive gases alarms and more - Presents a structured presentation that allows for quick reference of vital information

Download or read book Science and Technology of Electroceramic Thin Films written by O. Auciello and published by Springer Science & Business Media. This book was released on 1995-02-28 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electroceramic thin films hold out the promise of applications in entirely new generations of advanced microdevices that may revolutionise technology, creating multibillion dollar markets in the process. Less glamorous than the high-temperature superconductors, but probably just as important, are electrically conductive, ferroelectric, piezoelectric, pyroelectric, electro-optic, and magnetic films. The list of potential applications of films having these properties is virtually endless, but there are still some issues to be resolved before fully functioning devices reach the market. All these issues and more are discussed in Science and Technology of Electroceramic Thin Films, which provides one of the best, most up to date summaries of the field currently available.
