This book was released on 2009 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxide based dilute magnetic semiconductors (DMS) are key materials for development of next generation multifunctional spintronics devices such as spin transistors and magnetic random access memories. However, the success of the spintronics devices critically depends on electrical and magneto-transport properties of DMS. This thesis investigates the effect of growth temperature and oxygen pressure on structural, optical, and magneto-transport properties of cobalt-doped indium oxide (In2O3:Co) DMS thin films. Thin films were grown under different partial oxygen pressures and substrate temperatures on quartz and sapphire substrates using pulsed laser deposition (PLD) technique. Structural, electrical, optical, and magneto-transport properties have been measured using various characterization techniques such as x-ray diffractometer (XRD), UV-visible spectroscopy, temperature dependent magneto-transport set-up, and superconducting quantum design magnetometer. The crystallinity of the films increases with increasing growth temperature as well as oxygen pressure during the growth as revealed by XRD. Hall effect and temperature dependence resistivity measurements reveal that the electrical transport properties (carrier density, mobility, and resistivity) in these films can be tuned by changing the growth temperature as well as oxygen pressure. Bandgap, measured using optical measurement, decreases with decrease in carrier concentration obtained from electrical measurement. Magneto-transport properties such as temperature dependent resistivity and magneto-resistance were found to be very sensitive to the micro-structural properties such as crystallinity as well as oxygen defect. These results provide basic information regarding electronic and magnetic properties of indium oxide as a prospective DMS for future spintronics applications.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Four novel diamine adducts of bis(hexafluoroacetylacetonato)zinc [Zn(hfa)2·(diamine)] can be synthesized in a single step reaction. Single crystal x-ray diffraction studies reveal monomeric, six-coordinate structures. The thermal stabilities and vapor phase transport properties of these complexes are considerably greater than those of conventional solid/liquid zinc metal-organic chemical vapor deposition (MOCVD) precursors. Of the four complexes, bis(1,1,1,5,5,5-hexafluoro-2,4-pentadionato)(N,N '-diethylethylenediamine)zinc [Zn(hfa)2 ( N,N'-DEA)], is particularly effective in the growth of thin films of the transparent conducting oxide Zn- and Sn-doped In2O3 (ZITO) due to its superior volatility and low melting point of 64°C.

Available in PDF, EPUB and Kindle. Book excerpt: Transparent conducting materials are key elements in a wide variety of current technologies including flat panel displays, photovoltaics, organic, low-e windows and electrochromics. The needs for new and improved materials is pressing, because the existing materials do not have the performance levels to meet the ever- increasing demand, and because some of the current materials used may not be viable in the future. In addition, the field of transparent conductors has gone through dramatic changes in the last 5-7 years with new materials being identified, new applications and new people in the field. “Handbook of Transparent Conductors” presents transparent conductors in a historical perspective, provides current applications as well as insights into the future of the devices. It is a comprehensive reference, and represents the most current resource on the subject.

Abstract: Abstract of thesis entitled PREPARATION AND POST-ANNEALING EFFECTS ON THE OPTICAL PROPERTIES OF INDIUM TIN OXIDE THIN FILMS Submitted by WANG Rong Xin for the degree of Doctor of Philosophy at The University of Hong Kong in April 2005 Many opto-electronic devices, such as III-V compound devices, liquid crystal displays, solar cells, organic and inorganic light emitting devices, and ultraviolet photodetectors, demand transparent electrode materials simultaneously having high electrical conductance. To meet the requirements for particular applications, a great deal of basic research and studies have been carried out on the electrical and optical properties of these materials. As a most promising candidate for such materials, indium tin oxide (ITO) has attracted interest in recent years. Furthermore, ITO has many unique properties such as excellent adhesion on the substrate, thermal stability and ease of patterning. The deposition of high-quality ITO thin films is a key step for successful application of ITO thin films as transparent electrode materials. To obtain optimal electrical and optical properties of ITO films, the growth parameters and conditions must be determined. Moreover, the optical and electrical properties of ITO contact layers, which can either be on the top side or the bottom side of a device, are influenced by various post-deposition treatments. For the present work, ITO thin films were deposited on glass and quartz substrates using e-beam evaporation with different deposition rates. The influence of substrate material, deposition rate, deposition gas environment and post-deposition annealing on the optical properties of the films was investigated in detail. Atomic force microscopy, X-ray diffraction and X-ray photoemission spectroscopy was employed to obtain information on the chemical state and crystallization of the films. Analysis of these data suggests that the substrate material, deposition rate, deposition gas environment and post-deposition annealing conditions strongly affect the chemical composition and the microstructure of the ITO films and these in turn influence the optical properties of the film. Oxygen incorporation transfers the In O phase to the In O phase and removes metallic In to form both indium oxide 2 3-x 2 3 phases. Both of these reactions are beneficial for the optical transmittance of ITO thin films. Moreover, it was found that the incorporation and decomposition reactions of oxygen can be controlled so as to change the optical properties of the ITO thin films reversibly.

Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.
