Wiley International Edition. This book is the sixth edition of an elementary text on solid state physics for senior undergraduate and beginning graduate students of science and engineering. Solid state physics is concerned with the properties, often astonishing and often of great utility, that result from the distribution of electrons in metals, semiconductors, and insulators. This book also tells how the elementary excitations and imperfections of real solids can be understood in terms of simple models whose power and utility is now firmly established. Contents include: Crystal Structure, Reciprocal Lattice, Crystal Binding, Phonons I. Crystal Vibrations, Phonons II. Thermal Properties, Free Electron Fermi Gas, Energy Bands, Semiconductor Crystals, Fermi Surfaces and Metals, Plasmons, Polaritons, and Polarons, Optical Processes and Excitons, Superconductivity, Dielectrics and Ferroelectrics, Diamagnetism and Paramagnetism, Ferromagnetism and Antiferromagnetism, Magnetic Resonance, Noncrystalline Solids, Point Defects, Surface and Interface Physics, Dislocations, and Alloys.
