Description
Kittel's Introduction to Solid State Physics, Global Edition, has been the standard solid state physics text for physics majors since the publication of its first edition over 60 years ago. The emphasis in the book has always been on physics rather than formal mathematics. This book is written with the goal that it is accessible to undergraduate students and consistently teachable. With each new edition, the author has attempted to add important new developments in the field without impacting its inherent content coverage. This Global Edition offers the advantage of expanded end-of-chapter problem sets.
