To aquire kowledge of the fundamental paradigms of condensed matter physics, in particular with regard to the crystalline state. To integrate these paradigms with knowledge of Quantum Mechanics and Thermal Physics. To familiarize oneself with some of the fundamental techniques for material characterization. To understanding the metallic state, its thermodynamic properties and transport. To introduce the physical basis of semiconductors and their applications.
To have the the ability to derive some of the basic results of the models studied and of finding answers to relatively elementary extensions of the models, demonstrating understanding of the basic principles and their relationships.
