Defects in Solids

• Provides a thorough understanding of the chemistry and physics
  of defects, enabling the reader to manipulate them in the
  engineering of materials.

• Reinforces theoretical concepts by placing emphasis on real
  world processes and applications.

• Includes two kinds of end-of-chapter problems: multiple choice
  (to test knowledge of terms and principles) and more extensive
  exercises and calculations (to build skills and
  understanding).

• Supplementary material on crystallography and band structure
  are included in separate appendices.
