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.

This book was released on 2017 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we investigated whether the optical and electrical properties of indium tin oxide (ITO) films are degraded under laser irradiation below their laser ablation threshold. While performing multi-pulse laser damage experiments on a single ITO film (4.7 ns, 1064 nm, 10 Hz), we examined the optical and electrical properties in situ. A decrease in reflectance was observed prior to laser damage initiation. However, under sub-damage threshold irradiation, conductivity and reflectance of the film were maintained without measurable degradation. This indicates that ITO films in optoelectronic devices may be operated below their lifetime laser damage threshold without noticeable performance degradation.

This book was released on 2014-04 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: With dwindling energy reserves, Photovoltaic(PV) module which is one of the most promising renewable sources of energy is slowly becoming indispensable for world's electricity production paradigm. Due to the low electrical resistance and high optical transparency in the visible range of the electromagnetic spectrum, Transparent Conducting Oxide (TCO) thin film(TF)s have found application as window electrode for fabrication of solar cell. Besides TCOs have wide application in display devices and other optoelectronic devices. This book mainly focuses on the fabrication and study of the optoelectronic properties of TCO thin films with special reference to PV application. This book also includes the fabrication and study of a heterojunction II-VI semiconductor solar cell using TCO as front electrode. It also highlights different methods used for the study of optoelectrical and structural properties of TF (e.g. SEM, XRD, thickness measurement, optical band gap, mobility, determination of carrier type, carrier concentration, conductivity etc.). This book is designed to serve as a handbook for the beginners who want to work in the field of thin film technology.

Available in PDF, EPUB and Kindle. Book excerpt: "As a transparent conductive material, indium tin oxide (ITO) has been utilized as electrodes in liquid crystal displays, solar cells, heat reflecting films and gas sensors. In general, the desired properties are high conductance and transmission. However, due to the complexity of ITO, the film properties strongly depend on the deposition processes. In this study, the deposition conditions for ITO film were optimized to get both high conductivity and transmission. The emphasis was on investigating the effects of various deposition parameters, such as oxygen partial pressure, total gas flow, annealing conditions and power. These are the most critical parameters for ITO deposition. A mathematical model to describe the material properties as functions of these parameters for a CVC model 601 Sputterer was developed utilizing JMP IN software. Films with resistivity 3x10-4[omega]-cm and transmittance above 90% were achieved on glass and silicon substrates with 20 hours of annealing. The processing window (power: 120-150W, oxygen ratio: 6-10%) is, to the author's knowledge, the largest reported by literature. However, the ITO film properties (electrical and optical) variation between runs needs to be further reduced. Patterning of ITO was also investigated. High but controllable etch rates are desired. Both wet and dry etch processes were developed. The etch rate of 48nm/min was achieved by using HCL aqueous solution (4:1 HCl to DI water volumetric ratio, where HCl is the standard 37% HCl solution) with almost infinite selectivity between the ITO film and the photoresisit. For dry etch, the etch rate is 1nm/min with just argon as the working gas and the etching selectivity between the photoresist and the ITO film is 13.02. To etch 100nm ITO film, the photoresist needs to be at least 1.5um to serve as etching mask. This dry etch process still needs to be improved. A Schottky contact was successfully fabricated by using ITO as the metal. The electrical barrier height was calculated to be 1.01eV. The current-voltage characteristics were investigated as well"--Abstract.

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.

This book was released on 2013-05-13 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent electrodes (TEs) are a class of materials that make it possible to bring electrical current or potentials in close proximity to optically active regions without significant loss of optical energy. However, it is a challenge to decouple the electrical and optical properties of a material, as the property of conductivity is strongly coupled to the imaginary part of the refractive index. An ideal TE has high transparency in combination with very low electrical resistivity. The main objective of the thesis was to develop TEs which can replace expensive, scarce and fragile Indium Tin Oxide (ITO), the most widely used TE material in the industry today. The thesis contains original work on ultrathin metal film (UTMF)-based TEs, which are essential elements in a wide range of optoelectronics, consumer electronics and energy devices. It presents new designs and fabrication methods and demonstrates the efficient use of UTMF-TEs in organic light emitting diodes and solar cells, achieving similar levels of efficiency to that of state-of-the-art ITO.
