The material of this book was chosen in a simple manner to clarify the basic concepts of crystallography, structure properties of crystalline materials and the dependence of these properties on crystal structure. However, its contents were presented in terms of educational way to facilitate the handling of its scientific concepts.

This book contains seven chapters covering one semester course in solid-state physics. The sequence of content is: a brief review of bonding in solid materials, the characteristics of the solid-state crystal structure, the types of structural defects in crystalline materials, concept and various experimental methods for X-ray diffraction in crystalline materials, lattice vibrations and phonon concept, and more than 1300 solved MCQs, MMCQs and True and False questions. in addition to solved examples, exercises and problems.

This book can be considered as a useful reference for students of faculties of science and also for students studying materials science in the faculties of engineering or higher technical institutes.
