This third updated edition fills the gap between a general solid-state physics textbook and research articles by providing detailed explanations of the electronic, vibrational, transport, and optical properties of semiconductors. The approach is physical and intuitive rather than formal and pedantic. The textbook emphasizes understanding the physical properties of Si and similar tetrahedrally coordinated semiconductors. Each chapter is enriched by an extensive collection of tables of material parameters, figures, and problems. Many of these problems "lead the student by the hand" to arrive at the results.

Electronic Band Structures.- Vibrational Properties of Semiconductors, and Electron-Phonon Interactions.- Electronic Properties of Defects.- Electrical Transport.- Optical Properties I.- Optical Properties II.- Photoelectron Spectroscopy.- Effect of Quantum Confinement on Electrons and Phonons in Semiconductors.

Since the appearance of our book, Fundamentals of Semiconductors: Physics and Materials Properties, one of the questions we are asked most frequently is this: "is there a solution manual to this book?" In preparing the questions at the end of each chapter we have already tried to guide the readers to derive the answers by themselves using a step-by-step approach. Clearly this strategy did not work for everyone. We recognize that many of the questions in this book are quite challenging and often require reading of research papers to solve them. In response to readers demand we have - cided to provide solutions to some of the problems in this new edition. Since working through problems is an important and necessary part of the learning process in physics we will not give the solutions to all the problems. Instead, we hope to use the solutions to a number of selected problems in each ch- ter as an additional study help to the readers. We like to use these solutions to provide more in depth discussions to topics which may be too specialized for a typical course on semiconductor physics. By leaving enough unsolved problems and adding a few new ones there are still plenty of opportunities for both the instructors to choose problems for assignments and for students to test their understanding of the text.
