Condensed Matter Physics and Devices
To familiarize the students with the basics of condensed matter physics which form the basic for further studies in condensed matter physics. The students get acquainted with the crystal structure, properties of solids, superconductivity and magnetism which strengthens the theoretical base for research in contemporary fields of condensed matter physics like imperfect solids and nano particle physics. The students acquire abilities to undergo research or involve in business related to material science.
