This book provides some insight into chemical defects in crystalline solids, focusing on the relationship between basic principles and device applications. It is concerned with the chemical, optical and electronic consequences of the presence of defects in crystals.

The aim of this text is to provide some insight into chemical defects in crystalline solids. Chemical defects, which are mistakes or changes in the atomic make-up of the crystals, have far-reaching effects on the composition, optical properties and electronic properties of materials. The area is therefore of relevance to chemists, physicists, materials scientists and engineers. The book has been designed to be read by students with no prior knowledge of the subject, but with a background in basic chemistry and physics. It begins with relatively simple ideas but progresses into a discussion of complex materials, at the forefront of research in the field. The links between principles and applications have been strengthened in the text by the inclusion of a series of case studies. In addition, the crystal structures that are of most importance have been described throughout the book in a series of boxes, to provide a crystallographic reference within the text.

This book provides some insight into chemical defects in crystalline solids, focusing on the relationship between basic principles and device applications. It is concerned with the chemical, optical and electronic consequences of the presence of defects in crystals.

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.

About the Book: The book has been designed to cover all relevant topics in B.E. (Mechanical/Metallurgy/Material Science/Production Engineering), M.Sc. (Material Science), B.Sc. (Honours), M.Sc. (Physics), M.Sc. (Chemistry), AMIE and Diploma students. Students appearing for GATE, UPSC, NET, SLET and other entrance examinations will also find book quite useful.
