Relationship between structures of materials and their properties are outlined. It includes numerous problems, and solved examples. Applied Solid State Physics is a text/reference book for students studying a course in engineering and Masters in Solid State Physics. The text has been written with the aim of presenting the physical principles which explain different physical properties of materials. The exposition of the structure-property relationships in materials is the underlying theme of the book. Both the pure and applied aspects of physics of materials are presented. Solved examples, questions and problems are provided at the end of each chapter.
