Physics of Materials

Physics of Materials. Instructor: Dr. Prathap Haridoss, Department of Materials Engineering, IIT Madras. This course will discuss the approaches used to understand important properties of materials and the relationships between these properties. Elementary quantum mechanics, free electron theory of metals, and quantum mechanics will be used to understand material properties. The use of reciprocal lattice formation will be explored. Electronic conductivity, thermal conductivity, semiconductor behavior, optoelectronic materials, and superconductivity, will be some of the phenomena examined in the course. (from nptel.ac.in)
