Available in PDF, EPUB and Kindle. Book excerpt: In this work, we investigate the realization of p-type CuInOx thin films by RF magnetron sputtering using Cu2O: In2O3 target and study the effects of (i) post-deposition annealing and (ii) substrate heating during a deposition for controlling the optoelectronic and morphological properties. In the first part of the study, post-process annealing of the deposited films was performed at temperatures ranging from 100-900°C in O2 ambiance. The X-ray diffraction (XRD) analysis performed on the samples identified the presence of Cu2In2O5 phases along with CuInO2 or In2O3 for the films annealed above 500°C. A morphological study performed using SEM shows the crystallization and the grain growth with an increase in the annealing temperatures. Optical studies carried out on the films indicated a small bandgap change in the range of 3.4-3.6 eV during annealing.

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 Optical Characterization of Real Surfaces and Films

Download or read book Optical Characterization of Real Surfaces and Films written by K. Vedam and published by Academic Press. This book was released on 2013-10-22 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume of the highly respected Physics of Thin Films Serial discusses inhomogeneity in real films and surfaces. The volume, guest-edited by K. Vedam, follows the growth of thin films both from the surface of the substrate, and from the atomic level, layer by layer. The text features coverage of Real-Time Spectroscopic Ellipsometry (RTSE) and Reflectance Anisotropy (RA), two major breakthrough optical techniques used to characterize real time and insitu films and surfaces. In six insightful chapters, the contributors assess the impact of these techniques, their strengths and limitations, and their potential for further development.

This book was released on 2015-11-04 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transparent conducting metal oxide thin films received the attention of many researchers for application in transparent electronics such as heterojunction solar cells, gas sensors, electrochromic devices, optoelectronic devices etc. Cuprous oxide (Cu2O) and copper aluminum oxide (CuAlO2) are transparent oxides exhibiting p-type conductivity. The properties of these materials in thin film mainly depend on the method of preparation and deposition conditions maintained during film growth. This book restrains the optimized deposition conditions of Cu2O and CuAlO2 films deposited on glass substrates using dc reactive magnetron sputtering technique, and investigated their structural, composition, microstructure, surface morphology, optical and electrical properties.The promising approach to prepare device quality films for optoelectronic devices was discussed clearly in this book

Book Annealing Effects on Cu In  Ga Se  sub 2  and CuInSe sub 2  Thin Films

Download or read book Annealing Effects on Cu In Ga Se sub 2 and CuInSe sub 2 Thin Films written by Jason Gregory McDonald and published by . This book was released on 2005 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of my research is to study the effects of annealing on Cu(In, Ga)Se[sub2] (CIGS) and CuInSe[sub 2](CIS) thin films. Annealing polycrystalline films improves the films by minimizing secondary phases in the film and by increasing the crystal grain size. Annealing consists of heating the film to high temperatures, which varies between several hundred degrees to more than 500 degrees Celsius. The length of annealing time also affects the thin film. Films are annealed in a time frame from several minutes to several hours. Questions to be addressed are what preferred temperature to use for annealing and for what length of time. Furthermore, for repeated annealing of a film, would better results be found from annealing at increasing temperature with time held constant, or with increasing time while holding the temperature constant.
