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.

Book excerpt: This book describes important recent developments in fiber optic sensor technology and examines established and emerging applications in a broad range of fields and markets, including power engineering, chemical engineering, bioengineering, biomedical engineering, and environmental monitoring. Particular attention is devoted to niche applications where fiber optic sensors are or soon will be able to compete with conventional approaches. Beyond novel methods for the sensing of traditional parameters such as strain, temperature, and pressure, a variety of new ideas and concepts are proposed and explored. The significance of the advent of extended infrared sensors is discussed, and individual chapters focus on sensing at THz frequencies and optical sensing based on photonic crystal structures. Another important topic is the resonances generated when using thin films in conjunction with optical fibers, and the enormous potential of sensors based on lossy mode resonances, surface plasmon resonances, and long-range surface exciton polaritons. Detailed attention is also paid to fiber Bragg grating sensors and multimode interference sensors. Each chapter is written by an acknowledged expert in the subject under discussion.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Off-axis sputtering has been used to study two oxide thin film systems. The first study involved developing an epitaxially grown NiO/SrTiO3 heterostructure to be used for a negative index of refraction. The second used off-axis sputtering as a combinatorial approach to study the effects of doping and codoping of transparent conducting ZnO. A negative index of refraction should be possible by combining only intrinsic material resonances. We proposed that combining NiO, which has an antiferromagnetic resonance in the far infrared, and SrTiO3, which has a dielectric resonance in the far-infrared, can be used to achieve a negative refractive index of refraction in the far-infrared. These resonances can be shifted through changing temperature, doping, or through applying a magnetic field. A high quality epitaxially grown composite heterostructure and bulk ceramics have been fabricated. Preliminary measurements of the permeability and permittivity been taken for a bulk composite structure. The SrTiO3 ionic resonance can be seen in a reflection technique while the NiO antiferromagnetic resonance is easily seen in a transmission technique ZnO is a potential inexpensive replacement for indium tin oxide (ITO) as a high-end transparent conductor. However, ZnO has not replaced ITO in many applications such as flat-panel displays due to high resistivity and poor thermal stability. ZnO has been doped with many elements including Al, In and Ga. We proposed that codoping with both Al and In might result in size compensation which would lead to improved dopant solubility and therefore better electrical conductivity and stability. A high-throughput combinatorial approach was used to study codoping of ZnO with both Al and In. Measurement of the deposited composition spread suggests that codoping results in much improved conductivity. By adding 1% In to highly Al-doped ZnO (3-6%) the conductivity increases by an order of magnitude. Thermal annealing in a variety of atmospheres including air, vacuum and hydrogen results in some understanding of the difference in the two dopants. It was found that Al doping results in a higher carrier concentration than In doping, but any excess Al greatly decreases the mobility. In doping improves the mobility but with lower carrier concentrations. Calculations based on density functional theory support the experimental data, showing that Al is a shallower dopant than In. Unit cell volume comparisons between theory and experiment correspond well. The interplay between substitutional doping, oxygen vacancies, and possible adventitious H doping makes the doped ZnO system difficult to analyze definitively.
