Prerequisite: Basic knowledge of quantum mechanics, electromagnetism and solid state physics. The objective of this course is to cover the fundamental concepts of structural, electrical and optical properties needed to understand the behavior of the materials including conductors, semiconductors and dielectrics. The course will provide an overview of the electronic properties of materials with emphasis on fundamental physical models that describe the crystal structure, chemical bonding, energy band structure of solids, charge carrier transport in metals, semiconductors, metal-semiconductor junctions and semiconductor-semiconductor junctions. After attending the course the students should be able to understand the origin of electrical properties of materials and their relation to the operating principles of key devices used in modern day electronics.
