This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, the optical and electrical properties of cadmium stannate thin films were studied in order to determine how these properties depend on the deposition and heat treatment conditions used during film formation. Trends in band gap energy, transmittance, mobility, resistivity and carrier density were studied, as well as the growth rate and the indices of refraction and extinction. Optical data was primarily measured using variable angle spectroscopic ellipsometry. In the process of acquiring this data, a procedure for accurately determining the optical properties using variable angle spectroscopic ellipsometry was developed. Ultimately, samples achieved the highest quality when deposited in 5% atmospheric oxygen at room temperature and heat treated at 600 °C in contact with a cadmium sulfide layer in an argon atmosphere. It was found that oxygen content and film thickness may affect the heat treatment process, while temperature treatments below 600 °C will not sufficiently induce crystallization. Further study should be given to controlling the cadmium sulfide diffusion rate in order to optimize carrier density and mobility.

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.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made into the effect of rf magnetron deposition parameters on the resulting properties of chromium oxide thin films. The films were sputtered in an argon/ oxygen plasma environment with the main deposition parameters being the argon and oxygen flow rate, chamber pressure, deposition-time and the deposition power (forward and back). Tire effect of the sputter deposition regime which is controlled by the sputtering hysteresis phenomenon i.e. the reactive and metallic regimes, are expected to have a significant effect on the properties of the sputtered films and will have to be taken into account. The films were deposited on a range of substrates such as silicon, glass micro-slides and stainless steel 304 and the composition of the mainly amorphous sputtered films was determined through XPS, EDX and XRD. Optical characterisation and determination of optical constants was undertaken by transmission/reflection spectrophotometry, ellipsometry and Raman and FTIR analysis. Two designs of a solar thermal absorber (multilayer interference and tandem absorber) were designed and fabricated based on the optical constants measured by the methods previously stated and their performance analysed. The surface energy was calculated through measurement of the contact angle with three different liquids and the corrosion resistance of the films measured by OCP, linear sweep and EIS analysis in 3.5wt% NaCI solution. The mechanical properties were measured by nanoindentation, from which the hardness and elastic modulus of the samples could be obtained. The electrical properties were measured using a four point probe to calculate the thin film resistivity and the Kelvin probe analysis was used to measure the work function of the samples.

Available in PDF, EPUB and Kindle. Book excerpt: "You, 0 Sun, are the eye of the world You are the soul of all embodied beings You are the source of all creatures You are the discipline of all engaged in work" - Translated from Mahabharata 3rd Century BC Today, energy is the lifeline and status symbol of "civilized" societies. All nations have therefore embarked upon Research and Development pro grams of varying magnitudes to explore and effectively utilize renewable sources of energy. Albeit a low-grade energy with large temporal and spatial variations, solar energy is abundant, cheap, clean, and renewable, and thus presents a very attractive alternative source. The direct conver sion of solar energy to electricity (photovoltaic effect) via devices called solar cells has already become an established frontier area of science and technology. Born out of necessity for remote area applications, the first commercially manufactured solar cells - single-crystal silicon and thin film CdS/Cu2S - were available well over 20 years ago. Indeed, all space vehicles today are powered by silicon solar cells. But large-scale terrestrial applications of solar cells still await major breakthroughs in terms of discovering new and radical concepts in solar cell device structures, utilizing relatively more abundant, cheap, and even exotic materials, and inventing simpler and less energy intensive fabrication processes. No doubt, this extraordinary challenge in R/D has led to a virtual explosion of activities in the field of photovoltaics in the last several years.

Download or read book Investigation of Industrially-Suited Processes for Deposition of Oxide Thin Films by High Power Impulse Magnetron Sputtering written by Felipe de Campos Carreri and published by Fraunhofer Verlag. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this work is to investigate and to develop advanced HIPIMS processes for deposition of oxides, utilizing industrial-scale equipment and technology. Two classes of oxide materials were studied: insulating (aluminum oxide) and conducting oxides (indium-tin oxide and aluminum-doped zinc oxide). The electrical properties of the oxides have a significant influence on the process design, as the issues and approaches for deposition of insulating materials are fairly different from conducting materials. Different types of reactive process control were also investigated, utilizing optical emission spectroscopy to control the oxygen flow and lambda probes to control the discharge power. A non-reactive process was also studied for indium-tin oxide.

Download or read book High Performance Transparent Conducting Films of Cadmium Indate Prepared by RF Sputtering written by and published by . This book was released on 1996 with total page 12 pages. 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.
