Fundamentals of Semiconductors

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.
