The main topic of this book is quantum mechanics, as the title
indicates. It specifically targets those topics within quantum
mechanics that are needed to understand modern semiconductor
theory. It begins with the motivation for quantum mechanics and why
classical physics fails when dealing with very small particles and
small dimensions. Two key features make this book different from
others on quantum mechanics, even those usually intended for
engineers: First, after a brief introduction, much of the
development is through Fourier theory, a topic that is at the heart
of most electrical engineering theory. In this manner, the
explanation of the quantum mechanics is rooted in the mathematics
familiar to every electrical engineer. Secondly, beginning with the
first chapter, simple computer programs in MATLAB are used to
illustrate the principles. The programs can easily be copied and
used by the reader to do the exercises at the end of the chapters
or to just become more familiar with the material.

Many of the figures in this book have a title across the top.
This title is the name of the MATLAB program that was used to
generate that figure. These programs are available to the reader.
Appendix D lists all the programs, and they are also downloadable
