The book introduces students of materials engineering, materials science and related engineering disciplines to solid state physics with the needs of these target audiences in mind: It focuses on the basic concepts and their consequences and carefully develops the necessary formal framework without overwhelming the readers with mathematical and highly theoretical details. In addition, it provides direct connections to modern materials such as graphene photonics materials and to applications such as high-temperature superconductors and MOSFETs. Worked examples throughout the text help the readers to get to grips with the concepts of solid state physics and to consolidate their knowledge.
