This text presents a comprehensive study of various topics of solid state physics for the undergraduate and postgraduate students of pure and applied sciences, and engineering disciplines. The text is divided into 17 chapters. The first seven chapters deal with structure related aspects such as lattice and crystal structures, bonding, packing and diffusion of atoms followed by imperfections and lattice vibrations. Chapter 8 deals mainly with experimental methods for determining structures of given materials, while remaining chapters cover various physical properties of crystalline solids. The treatment of the text has been kept simple and coherent. A number of solved examples, brief summary and definitions of important terms are included in each chapter for better understanding of the subject.
