Book excerpt: In recent years, the possibility of employing laser interaction with surfaces as a surface diagnostic tool has attracted a great deal of attention. Optical second harmonic generation (SHG) and sum-frequency generation (SFG) have been proven to be most effective and versatile for surface and interfacial studies. By symmetry, these processes are forbidden in media with centrosymmetry, and can therefore be highly surface-specific. They have the advantages of being capable of high spatial temporal and spectral resolutions, suitable for in-situ, remote sensing of samples in hostile environment and applicable to all interfaces accessible to light. Indeed, they have been applied with great success to a large variety of surface and interfacial problems: probing adsorption and desorption of molecules from surfaces, measuring average molecular orientation of adsorbates, monitoring surface symmetry and surface phase transitions, conducting surface microscopy and spectroscopy, and many others. Here, we shall describe a few experiments recently carried out in our laboratory using these techniques.

This book was released on 2015 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorption mechanisms at buried interfaces are difficult to predict a priori, with many interactions to consider including those between the substrate and solvent, the substrate and adsorbate, and the solvent and adsorbate. Studies described in this thesis examine the roles these variables have on controlling interfacial behavior, including molecular adsorption and aggregation at solid/liquid interfaces. Specifically, second harmonic generation (SHG) was employed to characterize adsorption environments and adsorption energies at different silica/liquid interfaces, due to the technique's surface specificity. Additionally, time resolved fluorescence was used to quantify emission lifetimes within these same interfacial regions. By systematically changing the substrate, solvent identity, and adsorbate functionality, the impact of each contribution was identified and quantified. Initial studies examined the role played by interfacial pH in controlling adsorption. Above pH 5, silica surfaces become negatively charged and promote two distinct adsorption mechanisms. Adsorption due to these mechanisms requires very long equilibration times (>3hrs). Subsequent experiments studied the role played by solvent identity on interfacial solvation. At a methanol/silica interface a non-polar interfacial environment was produced, independent of solute choice. Non-polar solvents conversely create polar interfacial solvation environments. At these different solid/liquid interfaces, similarly structured coumarin dyes, C151 and C152, were examined. Slight changes in structure lead to differing behaviors at the surface, C151 terminates at monolayer coverage while C152 shows clear signs of multilayer formation. This observation is explained by the difference in hydrogen bonding opportunities for each adsorbate: C151 can accept and donate H-bonds while C152 can only accept H-bonds, resulting in more degrees of freedom for C152 at an interface and thus the possibility of aggregation.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an introduction to new optical methods for investigating the electronic, atomic, and magnetic properties of metallic surfaces and films. The methods have potentially valuable commercial applications and the book will be a useful guide to researchers in condensed matter physics and optics. The book begins with a chapter on linear Kerr spectroscopy and its application to magnetism and magnetic anisotropy effects. This is followed by two chapters discussing nonlinear magneto-optics, particularly the application of second harmonic light generation (SHG) to ultrathin films. The next chapter discusses time-resolved linear and second order reflectivity methods, and the final two chapters cover the electronic theory for nonlinear optics and nonlinear magneto-optics. These last chapters include discussions of current problems and directions for future research.

Available in PDF, EPUB and Kindle. Book excerpt: The physics and chemistry of surfaces is becoming more and more important as an exciting field of basic research as well as in devices and technology. The diagnoses and the conditioning of surfaces and studies of molecular interac tions with surfaces have made large advancements by using laser techniques. With its divisional meeting 1983 the Quantum Electronics Division of the European Physical Society tried to set up a forum where the latest ideas and achievements could be presented and discussed. The wide range of topics (gen eral surface spectroscopy, surface-enhanced optical processes, laser surface spectroscopy, laser-induced processes at surfaces) was deliberately chosen to provide an opportunity for specialists from one field to get acquainted with the techniques and results from others. This meeting took place in Mauterndorf, Austria, from March 9th to March 11th, 1983. Mauterndorf is a small village in the Austrian Alps, situated in a well-known skiing area. The conference was held in a medieval castle adapt ed as a conference center. These stimulating surroundings guaranteed a vivid exchange of ideas among the 98 participants from 17 nations. Among the numerous people engaged in the organization, our special thanks go to Mrs. I. Mandl and Mrs. B. Seeberg for doing a superb job in implementing the meeting arrangements and efficiently prompting the authors to deliver their manuscripts for this volume in time.
