Product Description
Data on the elastic properties of single crystals has increased dramatically since Professor Simmons completed his first book in 1965. While this book is a consolidation of his earlier work, it has been extensively updated and revised to include new material and references, is far more complete, and is presented in a more useful form.

This is actually a handbook consisting of computer printout in tabular format. It presents data on the elastic properties of single crystals collected from the literature through mid-1970 and the elastic properties of isotropic aggregates which are calculated according to the schemes of Voigt and Reuss for all materials, and Hashin and Shtrikman for materials with cubic symmetry. The tables include about 3000 determinations.

At present it is impossible to calculate the elastic properties of a random, macroscopically isotropic aggregate of crystals from the single crystal elastic constants, but bounds may be obtained for the aggregate properties from the single crystal constants. Accordingly the book tabulates the Voigt and Reuss averages for all materials for which single crystal data has been reported. Hashin and Shtrikman have shown that the Voigt and Reuss bounds could be improved, and they have developed expressions for the corresponding bounds of aggregates of cubic crystals.

In this book all four bounds (Voigt, Hashin, Shtrikman, and Reuss) are tabulated for cubic materials while Voigt and Reuss bounds only are tabulated for non-cubic materials. The elastic properties of aggregates are those in common use and include Young's modulus, shear modulus, Poisson's ration, bulk modulus, compressibility, velocity of compressional waves, and the velocity of shear waves. Although any two of these properties suffice to uniquely characterize a given material, all are tabulated because different sets are best suited for different uses. ... Read more

Product Description

Issues relating to the high-K gate dielectric are among the greatest challenges for the evolving International Technology Roadmap for Semiconductors (ITRS). More than just an historical overview, this book will assess previous and present approaches related to scaling the gate dielectric and their impact, along with the creative directions and forthcoming challenges that will define the future of gate dielectric scaling technology.

Product Description
This volume in the Handbook of Optical Constants of Solids is the first and only book to provide comprehensive coverage of refractive index and thermo-optic coefficients. It contains the refractive indexes and thermo-optic coefficients for nonlinear crystals, semiconductors, optical glasses, and fiber glasses. The Sellmeier coefficients of two physically meaningful Sellmeier equations are evaluated and are used to calculate these values throughout the normal transmission region of these optical materials. The author has also included analysis and explanations for some temperature-dependent optical devices/systems


* Presents the optical constants for over 70 technologically interesting crystals and commercial glasses
* Details various techniques for measuring the optical constants and mathematical models for analytical calculations of some data
* Includes thermo-optic coefficients that are necessary to calculate the refractive index of the optical material at any operating temperature
* Describes how all optical devices (both temperature dependent and independent) can be explained satisfactorily by using the twoSellmeier equations ... Read more

Product Description

This volume reviews the current status with respect to both theory and observation of the extragalactic distance scale. A sufficient accuracy is required both for a precise determination of the cosmological parameters and also in order to achieve a better understanding of physical processes in extragalactic systems. The "standard candles", used to set up the extragalactic distance scale, reviewed in this book include cepheid variables, RR Lyrae variables, novae, Type Ia and Type II supernovae as well as globular clusters and planetary nebulae.
