This course is designed to describe a basic knowledge of the key concepts in solid state physics that are relevant to the explanation of electrical, optical, and magnetic properties of materials. Student will engage in theoretical descriptions of crystal and electronic structure, lattice dynamics, electrical and optical properties of diff€erent materials (metals, semiconductors, dielectrics, magnetic materials and superconductors) based on classical and quantum physics principles. Through this course students can explain the relationship between basic physical principles and macroscopic properties of materials students will encounter in real life.
