Book Description
Thin transparent and electrically conductive films of tin doped indium oxide (ITO) were made by sintering of nanoparticle dispersions. The resistivity decreased to 1 - 10(exp -2) Omega cm upon treatment at 800 deg C, while the luminous transmittance remained high. The property evolution was connected with sintering and densification as studied by Scanning Electron Microscopy, X-ray Diffraction, X-ray Fluorescence and Elastic Recoil Detection Analysis.

Badeker in 1907 observed that some materials are optically transparent in the visible light and electrically conducting [1]. Because of the increasing interest in electrically and electronically active materials, the search for materials and the techniques for producing semi-transparent electrically conducting films have gained much importance. In an intrinsic stoichiometric material, it is not possible to have simultaneously high transparency (>80%%) in the visible region and high electrical conductivity (>103 Ω cm-1).

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 Description
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.

Book Description
Indium oxide thin films have been prepared by a pyrolitic method in which solution of 1 mol/litre indium (111) chloride in butylacetate has been sprayed onto a heated substrate of glass, using nitrogen as the carrier gas. The films show variation in the optical transmission and electrical sheet resistance with substrate temperature. A sheet resistance greater than 173 / and an average optical transmission in the visible range exceeding 80% were obtained. [Authors' abstract].
