Objectives

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.

Learning outcomes and competences

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.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Eligibility for exams

Presence in problem classes

Calculation formula of final grade

3 problems to be solved in classroom: X rating (0-100). Final Exam: Classification Y (0-100). Final Grade Z = Max (Y, 0.25 X +0.75 Y). Grade = Min (Z * 20, 17) To obtain more than 17 an extra examination is required. Note: In case of evidence of copying of the problems there is no admission to final exams. Problem dates to be determined.

Examinations or Special Assignments
