Mechanic and Dielectric Properties


Book Description

Mechanic and Dielectric Properties deals with the mechanical and dielectric properties of thin films. Topics covered range from the deposition and mechanical properties of superlattice thin films to the preparation of hard coatings by sputtering and arc evaporation. The use of thin films in microwave acoustics is also discussed, along with ferroelectric films for integrated electronics and the physics, chemistry, and technology of electrochromic tungsten-oxide-based thin films. Comprised of five chapters, this volume begins with an analysis of the growth, characterization, and mechanical behavior of films comprising multilayers primarily of metal and refractory metallic compound components. The next chapter reviews the mechanical properties of hard coatings prepared by sputtering and arc evaporation, together with the influence of multilayer and gradient structures, and of film crystallinity, crystal orientation, and morphology, on properties such as hardness, coating smoothness, and friction behavior. Subsequent chapters focus on the unique role played by piezoelectric films in signal processing devices utilizing bulk or surface acoustic waves; the properties and applications of ferroelectric films in integrated electronics; and the underlying physics and chemistry of electrochromic tungsten-oxide-based thin films. This book should be of interest to physicists.




Chemical-Mechanical Polishing of Low Dielectric Constant Polymers and Organosilicate Glasses


Book Description

As semiconductor manufacturers implement copper conductors in advanced interconnect schemes, research and development efforts shift toward the selection of an insulator that can take maximum advantage of the lower power and faster signal propagation allowed by copper interconnects. One of the main challenges to integrating a low-dielectric constant (low-kappa) insulator as a replacement for silicon dioxide is the behavior of such materials during the chemical-mechanical planarization (CMP) process used in Damascene patterning. Low-kappa dielectrics tend to be softer and less chemically reactive than silicon dioxide, providing significant challenges to successful removal and planarization of such materials. The focus of this book is to merge the complex CMP models and mechanisms that have evolved in the past decade with recent experimental results with copper and low-kappa CMP to develop a comprehensive mechanism for low- and high-removal-rate processes. The result is a more in-depth look into the fundamental reaction kinetics that alter, selectively consume, and ultimately planarize a multi-material structure during Damascene patterning.




Electromagnetic, Mechanical, and Transport Properties of Composite Materials


Book Description

In the design, processing, and applications of composite materials, a thorough understanding of the physical properties is required. It is important to be able to predict the variations of these properties with the kind, shape, and concentration of filler materials. The currently available books on composite materials often emphasize mechanical pro

Physics and Mechanics of New Materials


Book Description

This new volume covers new advances in materials science and engineering technology, focusing on practical rather than theoretical aspects that are useful for the design, fabrication, testing, and industrial application of advanced materials and structures. It provides an overview of modern ferrites with special attention to their structure, types, and properties, discusses the impact of technological change upon the application of selected materials and energy resources, and presents case studies in thermophysics and applied mechanics for engineering technology that illustrate the physical, chemical, and material properties of a range of modern materials.




Molecular Mechanics Across Chemistry


Book Description

The remarkable breadth of modern molecular mechanics is covered in this textbook, developed for an undergraduate or first-time course on molecular mechanics. With applications ranging from drug design to homogeneous transition metal catalysis, the book implements a case-study approach designed to give readers exposure to the relevance and utility of molecular mechanics, as well as the opportunity to study a particular problem and its solution in depth.




Properties of Perovskites and Other Oxides


Book Description

In this book some 50 papers published by K A Müller as author or co-author over several decades, amplified by more recent work mainly by T W Kool with collaborators, are reproduced. The main subject is Electron Paramagnetic Resonance (EPR) applied to the study of perovskites and other oxides with related subjects. This wealth of papers is organized into eleven chapters, each with an introductory text written in the light of current understanding. The contributions of the first editor on structural phase transitions have been immense, and because K A Müller and J C Fayet have published a review paper on the subject, the latter is reproduced in chapter VII. Not related to EPR is a part of chapter VIII on the dipolar and quantum paraelectric behavior with dielectric studies. In chapter X two papers proving the existence of Fermi glasses are reproduced.The year 1986 bears some significance: early in this year the paper by Bednorz and Müller on the possible observation of superconductivity was published. This resulted in a substantial shift in the paradigm of condensed matter physics, to which the present first editor has contributed scientifically with others and which will be reviewed in a second volume.




Mechanics of Agricultural Materials


Book Description

The importance of economical production of agricultural materials, especially crops and animal products serving as base materials for foodstuffs, and of their technological processing (mechanical operations, storage, handling etc.) is ever-increasing. During technological processes agricultural materials may be exposed to various mechanical, thermal, electrical, optical and acoustical (e.g. ultrasonic) effects. To ensure optimal design of such processes, the interactions between biological materials and the physical effects acting on them, as well as the general laws governing the same, must be known.The mechanics of agricultural materials, as a scientific discipline, is still being developed, and therefore has no exact methods as yet, in many cases. However, the methods developed so far can already be utilized successfully for designing and optimizing machines and technological processes.This present work is the first attempt to summarize the calculation methods developed in the main fields of agricultural mechanics, and to indicate the material laws involved on the basis of a unified approach, with all relevant physico-mechanical properties taken into account.The book deals with material properties, gives the necessary theoretical background for description of the mechanical behaviour of these materials including modern powerful calculation methods and finally discusses a large number of experimental results. Many of them can only be found in this book. Special attention is paid to the unified approach concerning theory and practice.The systematic treatment of the material makes the book useful to a wide circle of designers, researchers and students in the field of agricultural engineering. The book can also be used as a textbook at technical and agricultural universities.
