Book Description
Transparent conducting thin films of metal oxides, doped metal oxides, and carbon nanotubes (CNTs), have been produced using various deposition techniques, including: Aerosol Assisted Chemical Vapour Deposition (AACVD), Atmospheric Pressure Chemical Vapour Deposition (APCVD), and Spray Coating. The resultant thin films were tested for their performance in a number of applications, including: Low emissivity ('Low-E') glazing, photovoltaic electrode materials, gas sensing and photocatalysis. AACVD was shown as a viable, and attractive, deposition technique for the synthesis of tin oxide, and doped tin oxide thin films, which allows for controllable doping levels, crystallinity, and surface structure. The tailoring of these physical attributes allows for enhanced performance of the functional properties of the films, whereby, a lower growth temperature produced highly transparent, highly conductive coatings with a low haze value for 'Low-E' applications, whereas, higher growth temperatures produced the high electrical conductivity, transparency, and light scattering properties required for high performance electrodes in thin film photovoltaics. In addition, a dual coating methodology was developed using both AACVD, and APCVD, to grow tin oxide thin films in a rapid timescale, but with modified surface structures showing changes to the short range waviness, kurtosis, and the surface area. Growth of carbon nanotubes, using CVD, was investigated over a range of metal catalysts, with varying Pauling electronegativity values, and over a range of temperature, methane, and hydrogen conditions. A growth mechanism has been postulated, whereby, the electronegativity of the metal catalyst, and the solubility and diffusion of the carbon through that catalyst, affects the type and properties of the carbon structure produced. To the authors knowledge, this is the first reported growth of MWCNTs using a chromium solo-metal catalyst, and the first reported growth of the unique 'carbon nanofibres' which were produced using gold and silver metal catalysts. Functionalisation of SWCNTs using a microwave reflux process was shown to yield sulphonate and sulphone modified nanotubes, which are highly soluble in water and able to undergo spray coating to produce carbon nanotube, nanonet transparent conducting thin films. The functionalisation process was shown to be reversible upon heating of the modified nanotubes. AACVD has been deemed unable to produced doped zinc oxide transparent conducting films. However, undoped zinc oxide films were produced. They displayed a high photocatalytic action in the degredation of stearic acid, and a UV light induced superhydrophilicity. The modification and deposition techniques, established throughout this work, were utilised to form transparent, hybrid, metal oxide-CNT coatings, for gas sensing. The hybrid materials displayed enhanced response times to combustible target gases, which has been attributed to the catalytic effects of the exposed carbon nanotube surfaces; and to the spillover of adsorbed oxygen from the active nanotubes to the metal oxide surface.

Book Description
Transparent conducting oxides (TCO) are a special class of materials that possess both the properties of optical transparency and electrical conductivity. They find use in various applications such as flat panel displays, light-emitting diodes, solar cells, touch screens, smart windows, etc. Some of the most well-known and widely used TCOs are ZnO doped with Al, In2O3 doped with Sn, and SnO2 doped with F. All these TCOs are n-type in nature and show n-type conductivity. On the contrary, p-type TCOs are not very common, and due to their inherent low mobility, it is very challenging to synthesize highly conductive p-type TCOs. This has, in turn, stunted the growth of transparent electronics, which requires both n-type and p-type TCOs with good conductivity. The pursuit of viable p-type TCO has led to a group of materials called as delafossites. Delafossites have the general chemical formula CuMO2, where Cu is a positive monovalent cation (Cu+), M is a trivalent cation (3+ metals like Ga, Al, Fe, In, etc.), and oxygen is a negative divalent anion (O2−). CuGaO2 has grown in popularity as one of the most researched p-type delafossites as the demand for novel p-type TCO has grown. This dissertation focuses on the deposition, synthesis, optimization, and post-deposition processing of CuGaO2 p-type TCO thin films deposited using the sputtering technique. The films were deposited using single or dual-target sputtering using either stoichiometrically mixed targets of Cu2O and Ga2O3 or by using Ga2O3 and Cu targets. The films displayed favorable tunable attributes and diverse film compositions with varying deposition parameters and post-deposition treatments. By varying the annealing ambiance, films containing CuGa2O4, a secondary phase of CuGaO2, were also synthesized and studied. The etch feasibility of any thin film is of prime importance for its use in any practical application. The etch feasibility of CuGaO2 films in various acids was also studied and reported in this dissertation.

Book Description
This book is about thin films; what they are, how they are prepared, how they are characterized, and what they are used for. The contents of this book not only showcase the diversity of thin films, but also reveals the commonality among the work performed in a variety of areas. The chapters in this volume are based on invited papers presented by prominent researchers in the field at a Symposium on "Thin Films: Preparation, Characterization, Applications" at the 221st National Meeting of the American Chemical Society held in San Diego, California. The coverage of the symposium was extensive; topics ranged from highly-ordered metal adlayers on well-defined electrode surfaces to bio-organic films on non-metallic nanoparticles. An objective of this book is for the readers to be able to draw from the experience and results of others in order to improve and expand the understanding of the science and technology of their own thin films systems.

Book Description
The challenge for producing “invisible” electronic circuitry and opto-electronic devices is that the transistor materials must be transparent to visible light yet have good carrier mobilities. This requires a special class of materials having “contra-indicated properties” because from the band structure point of view, the combination of transparency and conductivity is contradictory. Structured to strike a balance between introductory and advanced topics, this monograph juxtaposes fundamental science and technology / application issues, and essential materials characteristics versus device architecture and practical applications. The first section is devoted to fundamental materials compositions and their properties, including transparent conducting oxides, transparent oxide semiconductors, p-type wide-band-gap semiconductors, and single-wall carbon nanotubes. The second section deals with transparent electronic devices including thin-film transistors, photovoltaic cells, integrated electronic circuits, displays, sensors, solar cells, and electro-optic devices. Describing scientific fundamentals and recent breakthroughs such as the first “invisible” transistor, Transparent Electronics: From Synthesis to Applications brings together world renowned experts from both academia, national laboratories, and industry.
