This book was released on 1991 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical second harmonic generation has proven to be a powerful tool for studying interfaces. The symmetry properties of the process allow for surface sensitivity not available with other optical methods. In this thesis, we take advantage of these symmetry properties SHG to study a variety of interesting systems not previously studied with this technique. We show that optical second harmonic generation is an effective surface probe with a submonolayer sensitivity for media without inversion symmetry. We demonstrate the technique at a gallium arsenide surface, exploiting the different symmetry properties of the bulk and surface of the crystal to isolate the surface contribution. We also demonstrate that optical second harmonic generation can be used to determine the anisotropic orientational distribution of a surface monolayer of molecules. We apply the technique to study homogeneously aligned liquid crystal cells. To further explore the LC-polymer interface, we used SHG to study the surface memory effect. The surface memory effect is the rendering of an isotropic interface anisotropic by putting it in contact with an anisotropic bulk. Last, we describe some preliminary measurements of a time-resolved spectroscopic study of the phenomenon of second harmonic generation in a gas. The construction of a 500 microjoule pulsed, tunable laser source is described.

Book excerpt: Conference Overview and the Role of Chemistry in High-Temperature Materials Science and Technology LEO BREWER Department of ChemistIy, University of California, and Materials and Chemical Sciences Division, Lawrence Berkeley Laboratory, 1 Cyclotron Road, Berkeley, CA 94720 I don't want to compete with the fascinating historic account that John Drowart gave us, but I would like to go through the history of high don't get the reaction that I get from temperature symposia. I hope I some of my classes when I say, "Remember when such-and-such hap pened during the War?" And I get this blank look, and one of the students will say, "I wasn't born until after the Korean War. " Neverthe less, during World War II, many people in the high-temperature field had their first initiation. But there was one handicap. Owing to security measures, they were not able to interact with one another. Following the War, it was recognized that the high-temperature field was going to expand to meet the demands for materials with unique properties. To meet the demands for new fabrication techniques, it was important to establish better communications among various people. High-tempera ture symposia were established at that time and have continued very frequently, and I'd like to point out why they are especially important for this field. One problem is that it is not easy to work at high temperatures.

Book Synopsis Organic Molecules for Nonlinear Optics and Photonics by : J. Messier
Download or read book Organic Molecules for Nonlinear Optics and Photonics written by J. Messier and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonics is being labelled by many as the technology for the 21st century. Because of the structural flexibility both at the molecular and bulk levels, organic materials are emerging as a very important class of nonlinear optical materials to be used for generating necessary nonlinear optical functions for the technology of photonics. Since the last NATO advanced research workshop on "Polymers for Nonlinear Optics"held in June 1988, at Nice - Sophia Antipolis, France. there has been a tremendous growth of interest worldwide and important development in this field. Significant progress has been made in theoretical modeling, material development, experimental studies and device concepts utilizing organic materials. These important recent developments provided the rationale for organizing the workshop on "Organic Materials for Nonlinear Optics and Photonics" which was held in La Rochelle, France, in August 1990. This proceeding is the outcome of the workshop held in La Rochelle. The objective of the workshop was to bring together scientists and engineers of varied backgrounds working in this field in order to assess the current status of this field by presenting significant recent developments and make recommendations on future directions of research. The workshop was multidisciplinary as it had contributions from chemists, physicists, materials scientists and device engineers. The participants were both from industries and universities. The workshop included plenary lectures by leading international scientists in this field, contributed research papers and a poster session. Panel discussion groups were organized to summarize important developments and to project future directions.
Book Synopsis Laser Spectroscopy and Photochemistry on Metal Surfaces by : Hai-Lung Dai
Download or read book Laser Spectroscopy and Photochemistry on Metal Surfaces written by Hai-Lung Dai and published by World Scientific. This book was released on 1995 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using lasers to induce and probe surface processes has the advantages of quantum state specificity, species selectivity, surface sensitivity, fast time-resolution, high frequency resolution, and accessibility to full pressure ranges. These advantages make it highly desirable to use light to induce, control, or monitor surface chemical and physical processes. Recent applications of laser based techniques in studying surface processes have stimulated new developments and enabled the understanding of fundamental problems in energy transfer and reactions. This volume will include discussions on spectroscopic techniques, energy transfer, desorption dynamics, and photochemistry.

Book Synopsis Maxwell Displacement Current And Optical Second-harmonic Generation In Organic Materials: Analysis And Application For Organic Electronics by : Mitsumasa Iwamoto
Download or read book Maxwell Displacement Current And Optical Second-harmonic Generation In Organic Materials: Analysis And Application For Organic Electronics written by Mitsumasa Iwamoto and published by World Scientific. This book was released on 2021-06-22 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: The probing and modeling of carrier transport in materials is a fundamental research subject in electronics and materials science. According to the Maxwell electromagnetic field theory, there are two kinds of currents, i.e., conduction current and Maxwell displacement current (MDC). The conduction current flows when electronic charges, e.g., electrons and holes, are conveyed in solids, whereas MDC is the transient current that is generated due to the change of electric flux density. The source of conductive current is charged particles, i.e., electrons, holes, ions, etc., and the source of MDC is also the charged particles. It is therefore anticipated that we can probe and model carrier transport in materials, in terms of 'MDC'. In other words, we can find a novel way for modeling and analyzing materials on the basis of Dielectric Physics Approach, on focusing dielectric polarization phenomena. Maxwell Displacement Current and Optical Second-Harmonic Generation are basically dielectric phenomena. The aim of this book is to show the dielectric physics approach for the study of molecular materials and organic electronics devices related to carrier transport and dielectric polarization, on focusing Maxwell Displacement Current and Optical Second-Harmonic Generation in Organic Materials from viewpoints of Analysis and Application for Organic Electronics.
