This thesis deals with the characterization of interfaces by elastic light scattering and profilometry. The sensitivity of scattering measurements to surface topography were used in two major ways. It was shown that surface reactions in a liquid-solid interface can be monitored in situ in terms of changes in surface roughness.

These results are derived from the exact solutions for elastic wave scattering from such interfaces developped in the first part of the book. Comparisons of numerical solutions of special problems with Characterization of Interfaces by Elastic Light Scattering and Profilometry book analytical solutions are given and it is shown how the latter help to simplify the numerical treatment.

In order to characterize interface roughness scattering, two-dimensional electron gas (2DEG) mobility in (4 1 1)A and (1 0 0) selectively-doped In Ga As/In Al As quantum well (QW) HEMT structures, which were grown on InP substrates by molecular beam epitaxy, with a gate contact was measured at 20 K as a function of sheet electron concentration (N s) by changing gate by:   Elastic and diffractive scattering: the interface of soft and hard processes in QCD: proceedings of the International Conference (third "Blois Workshop") on Elastic and Diffractive Scattering, Northwestern University, Evanston, IL, USA May Composite materials are usually made in layered structure, where two adjacent materials are bonded together along their common faces.

Therefore, the inspection technique for determining the quality of the bonding interface is of great interest. The elastic wave scattering method for characterization is often used for this purpose[1].Author: M. Kitahara, J.-H. Yin. Polymer Characterization By Laser Light Scattering.

The application of quasi-elastic light scattering for the determination of particle size distributions is reviewed. The basic principles and assumptions on which the method relies are presented on an introductory level.

The practical performances are illustrated by different results including results obtained by round-robin comparative studies. In this paper we present some theoretical and experimental results on the characterization of roughness in thin films and multilayers by scattering techniques.

Particular attention is focussed on the difference between specular and diffuse scattering and on correlated roughness between interfaces. Using Quasi-Elastic Light Scattering To Study Particle Size Distributions in Submicrometer Emulsion Systems.

In the case of inelastic light scattering spectroscopy or Raman spectroscopy, the spectrum is created due to light scattering from vibrations in molecules or optical phonons in solids.

We will show that light scattering spectroscopic techniques, both elastic and inelastic, are emerging as very useful tools in material and environmental science.

Langmuir 1. Roughness determines many functional properties of surfaces, such as adhesion, friction, and (thermal and electrical) contact conductance. Recent analytical models and simulations enable quantitative prediction of these properties from knowledge of the power spectral density (PSD) of the surface topography.

The utility of the PSD is that it contains statistical information that is unbiased by. Containing more than equations and nearly drawings, photographs, and micrographs,this reference surveys key areas such as optical measurements and in-line calibration methods.

It describes cleanroom-based measurement technology used during the manufacture of silicon integrated circuits and covers model-based, critical dimension, overlay. Dynamic light scattering (DLS) is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution.

In the scope of DLS, temporal fluctuations are usually analyzed by means of the intensity or photon auto-correlation function (also known as photon correlation spectroscopy or quasi-elastic light scattering).

In this contribution, we present an optical setup for performing correlative single-particle imaging using laser light-sheet illumination: the first detection channel records elastic light scattering (Rayleigh/Mie), while the second channel detects inelastic light scattering (Raman) or fluorescence.
