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: This book primarily covers the fundamental science, synthesis, characterization, optoelectronic properties, and applications of metal oxide nanomaterials. It discusses the basic aspects of synthetic procedures and fabrication technologies, explains the related experimental techniques and also elaborates on the current status of nanostructured oxide materials and related devices. Two major aspects of metal oxide nanostructures – their optical and electrical properties – are described in detail. The first five chapters focus on the optical characteristics of semiconducting materials, especially metal oxides at the nanoscale. The following five chapters discuss the electrical properties observed in metal oxide-based semiconductors and the status quo of device-level developments in a variety of applications such as sensors, transistors, dilute magnetic semiconductors, and dielectric materials. The basic science and mechanism behind the optoelectronic phenomena are explained in detail, to aid readers interested in the structure–property symbiosis in semiconducting nanomaterials. In short, the book offers a valuable reference guide for researchers and academics in the areas of material science and semiconductor technology, especially nanophotonics and electronics.

This book was released on 2013 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indium Tin Oxide (ITO) is a transparent conducting oxide that is used in at paneldisplays and optoelectronics. Highly conductive and transparent ITO lms arenormally produced by heating the substrate to 300 C during deposition excluding plastics to be used as a substrate material. This thesis reports on an investigation whether or not dual ion beam sputtering can be used to create high quality ITO lms at room temperature. The e ect of exposing the sample to an atomic versusmolecular oxygen ux during deposition was investigated. The vacuum chamber ofthe Texas State dual ion beam sputtering system was refurbished resulting in a lowering of the base pressure from 3x106 torr to 1.3x107 torr. Thin ITO lms on glass and silicon substrates were made by reactive dual ion beam sputtering using an atomic oxygen assist beam and a molecular oxygen assist beam. The optical and electrical properties of the deposited lms were characterized by ellipsometry and four point probe measurements. The lm thickness and the ITO's optical properties, i.e. refraction and extinction coe cient, were determined from the ellipsometry data for lms sputtered at di erent oxygen ow rates (1-5 sccm). This data was used to calculate the resistivity and absorption coe cient of the sputtered ITO. The resistivity of the samples sputtered with atomic oxygen were lower than the resistivity for the samples made with molecular oxygen, achieving a minimum value of 2.67x103 cm. This value is comparable to what has been obtained by others using ion beam sputtering. The gure of merit (FOM), i.e. = , was calculated from the measurement data. The largest value obtained for the FOM was 0.08 1 Films sputtered with atomic oxygen had a FOM which was systematically 1.2 to 5 times larger than lms sputtered with molecular oxygen. Part of the work described in this thesis was presented at the spring 2012 meeting of the Texas Section of the American Physical Society.

Download or read book Transparent Electronics written by Antonio Facchetti and published by John Wiley & Sons. This book was released on 2010-03-25 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
