Synopsis

This book on electrical, optical, magnetic and thermal properties of materials differs from other introductory texts in solid state physics. First, it is written for engineers, particularly materials and electrical engineers, who want to gain a fundamental understanding of semiconductor devices, magnetic materials, lasers, alloys, and so forth. Second, it stresses concepts rather than mathematical formalism. Third, it is not an encyclopedia: The topics are restricted to material considered to be essential and which can be covered in one 15-week semester.The book is divided into five parts. The first part, "Fundamentals of Electron Theory," introduces the essential quantum mechanical concepts needed for understanding materials science; the other parts may be read independently of each other. Many practical applications are discussed to provide students with an understanding of electronic devices currently in use. The solutions to the numerical problems are given in the appendix. Previous editions have been well received by students and teachers alike. This third edition has again been thoroughly revised and brought up to date to take into account the explosive developments in electrical, optical, and magnetic materials and devices. In particular, the book contains expanded sections on flat-panel displays (liquid crystals, electroluminescent devices, and field-emission and plasma displays) as well as discussions of recent developments in ferro- and piezoelectricity, magneto-optical memories, photonic and magnetoresistive devices, blue- and green-emitting LED's, and dielectric and thermoelectric properties. Rolf E. Hummel is Professor of Materials Science at the University of Florida, Gainesville. He received his Ph.D. in 1963 from the University of Stuttgart, Germany, and the Max-Planck Institute for Materials Research, also in Stuttgart. His previous publications include Optical Properties of Metals and Alloys (1971) Electro- and Thermo-transport in Metals and Alloys (1977), the two-volume Handbook of Optical Properties (ed.) (1996) and Understanding Materials Science (1998).

Synopsis

This introduction to materials science for students of engineering and physics and for the interested general public examines not only the physical and engineering properties of virtually all kinds of materials, but also their history, uses, development, and some of the implications of resource depletion and materials substitutions. It covers all topics normally taught in a one-semester course on materials, but from an entirely novel perspective: the role materials have played throughout history in the development of mankind and technologies.The text thus begins with a discussion of the first human uses of materials during the stone and copper—stone ages. It then turns to the fundamental mechanical properties of materials and mechanisms for changing these. The historical developments of the bronze age are used to introduce a treatment of the properties of alloys and compounds. Next, A discussion of the atomic basis of materials properties leads to discussions of the iron age, of the role of iron and steel in history and technology, and of the degradation of materials (corrosion and its prevention). The historical overview concludes with an explanation of the history and properties of electronic materials (electrical, magnetic, optical, and thermal). Finally, a perspective is given on the history, science and technology of glass, ceramics (stoneware, earthenware, porcelain, high-tech ceramics), natural fibers (wood, cotton, silk, etc.) and on synthetic plastics. The concluding chapters consider economic and environmental concerns(recycling, waste disposal, world resources, prices) and ask what does the future hold?
