This book was released on 2015-02-04 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book we have discussed the preparation and characterization of CdO thin films using RF reactive magnetron sputtering technique. The deposition parameters such as oxygen partial pressure, substrate temperature and film thickness are optimized for producing good quality films. Systematic characterization of as deposited and annealed films has been discussed from the crystal structure, surface morphology, film composition, optical and electrical properties. The films prepared under optimized conditions are tested for gas sensing characteristics towards ammonia gas.

Available in PDF, EPUB and Kindle. Book excerpt: The authors are examining various spinel-structured thin films (e.g., Cd2SnO4, Zn2SnO4) to develop higher-quality transparent conducting oxides (TCO) than more conventional materials such as indium tin oxide. Here, the authors report on cadmium indate (CdIn2O4, CIO), which is another member of this family. Thin films of CIO were deposited by radio-frequency (RF) magnetron sputtering, from an oxide target, onto borosilicate glass substrates. The variables included the substrate temperature, sputtering gas composition, and pressure. Film properties were measured before and after heat treatment. Characterization involved Hall effect measurements, optical and infrared spectrophotometry, X-ray diffraction, and atomic-force microscopy. Film resistivities as low as 2.3 × 10−4 [Omega] cm were achieved for a film thickness of 0.55 [mu]m. The transmittance was 90% in the visible region of the spectrum, without correction for substrate losses and without an anti-reflection coating. The plasma resonance occurred at longer wavelengths than for other materials and this, with a bandgap of approximately 3.1 eV, presents a wide window for optical transmittance. The highest mobility was 54 cm2 V−1 s−1 and the highest carrier concentration was 7.5 × 102° cm−3.

Book excerpt: The second edition of this book focuses on the synthesis, design, and application of semiconducting metal oxides as gas sensing materials, including the gas sensing mechanism, and modification methods for sensing materials, while also providing a comprehensive introduction to semiconductor gas sensing devices. As an essential part of IoT (Internet of things), gas sensors have shown great significance and promising prospects. Therefore, studies on functional mesoporous metal oxides, one of the most important gas sensing materials based on their unique Knudsen diffusion behavior and tailored pore structure, have increasingly attracted attention from various disciplines. The book offers a valuable reference guide to metal oxide gas sensing materials for undergraduate and graduate students alike. It will also benefit all researchers who are involved in synthesis and gas sensing of metal oxides nanomaterials with relevant frontier theories and concepts. Engineers working on research and development of semiconductor gas sensors will also find some new ideas for sensor design.

Available in PDF, EPUB and Kindle. Book excerpt: Nano-indentation studies indicated that the hardness and the reduced modulus of the film are sensitive to the N2/Ar ratio of gas flow during sputtering. AFM studies revealed that the films become smoother as the N2/Ar ratio is increased. XPS data indicated the existence of C-N phases in the as-deposited films. The study of oxidation kinetics of RF sputter deposited SiCN thin films, using XPS, suggest that N2 co-sputtering helps to suppress the formation of a surface oxide, by allowing un-bonded Si to bond with N and C inside the vacuum chamber as opposed to bonding with O in atmosphere.

This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental investigation of SnO2 and ZnO thin films with emphasis on their use in solid state gas detection is discussed. Methods of thin film preparation, described here, include the chemical vapor deposition (CVD) technique for SnO2 films and the radio frequency sputtering technique for SnO2 and ZnO films. The use of Auger electron spectroscopy, (AES), transmission electron microscopy, (TEM) and x ray diffractometry, (XRD) in the analysis of these films is reported. Careful selection of the most useful films are made by applying these techniques to the films prepared here. The electrical stability and gas sensitivity response of rf sputtered films are studied. Information regarding the mechanisms involved in gas detection are also presented. Some preliminary device structures using these films along with well-established techniques for planar processing are also reported.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a fundamental discussion, latest research & developments, and the future of thin films and photoenergy materials, two developing areas that have the potential to spearhead the future of industry. Photoenergy materials are expected to be a next generation key material to provide secure, safe, sustainable and affordable energy. Photoenergy devices are known to convert the sunlight into electricity. This type of devices is very much simple in design with having a major advantage with their structure as stand-alone systems to provide outputs up to megawatts. They have been applied as a power source, solar home systems, remote buildings, water pumping, megawatt scale power plants, satellites, communications, and space vehicles. With such a list of enormous applications, the demand for photoenergy devices is growing every year. On the other hand, thin films coating, which can be defined as fusion of surface science, materials science, and applied physics, are progressing as a unified discipline of scientific industry. A thin film can be termed as a very fine or thin layer of material coated on a particular surface, that can be in the range of a nanometer in thickness to several micrometers in size. Thin films are being applied it a number of fields ranging from protection purposes to electronic semiconductor devices.
