The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.

Main themes

This course is an introduction to solid state physics. As such, we will deal with the different thermal and electric properties of solids. We will focus upon the application of basic concepts to semi-conductors (micro-electronic and technical applications for detecting charged particles) and to superconductivity.


a. Course contribution to the LO reference framework (programme LO)

LO1: 1.1, 1.4, 1.6

LO2: 2.4.

LO3: 3.2, 3.5

LO6:6.3, 6.4


b. Specific formulation of programme LOs for this course

At the end of this course, the student will be able:

1. to identify the main crystalline structures and their symmetries, both for the spatial and reciprocal networks.

2. to compare the different types of crystalline bonds.

3. to apply analytical mechanics to periodic structures to deduce their thermal properties.

4. to describe the vibrations of a crystal in terms of phonons.

5. to apply statistical mechanics to a gas of electrons to deduce their thermal and electrical properties.

6. to establish how a periodic potential produces an energy band structure.

7. to deduce the properties of semi-conductors in the solids band structure.

8. to explain the behaviour of a diode and a transistor starting from the properties of semi-conductor crystals.

9. to discuss the properties of superconductors in the light of different phenomenological and/or microscopic models.
