- Knowledge and understanding:
The course intends to provide an introduction to solid state physics, with
a particular focus on the thermal and electric properties in crystalline
structures
- Applying knowledge and understanding:
At the end of the learning process, the students will acquire the basic
knowledge that is needed to manage a large variety of theoretical tools
for the calculation of transport properties in solid state materials.

Adequate Knowledge of Quantum Mechanic

The course is organized in 68 hours of frontal lectures.
Attendance is not compulsory but strongly recommended.

The examination consists in an oral interview based on the discussion of
the topics treated during the course, with a typical duration of 40
minutes. Together with the evaluation of the degree of knowledge and
understanding reached by the student, the interview is aimed to evaluate
the students' ability in managing solid state problems.
