"The Fundamentals of Solid State Engineering", in its' third edition, is an excellent and up-to-date introduction to Solid State Engineering with a particular emphasis on semiconductor physics, in which the author is a world-leading researcher.

I personally adopted "The Fundamentals of Solid State Engineering" as the basis for an undergraduate course on opto-semiconductors and found the book clear, comprehensive and highly pedagogical. I believe that this is the result of it being refined as the support for the Solid State Engineering lecture course at Northwestern University over many generations of students. I can highly recommend the text to anyone seeking to develop a solid foundation in this field.
