Prerequisites: General Physics 1 and 2(point dynamics, oscillations, Maxwell equations), Quantum Physics (quantum operators, eigenvalues and eigenvectors), Structure of Solids (space and point groups, diffraction from a crystal)
Target skills and knowledge: The course aims at applying the methods of quantum mechanics to the description of the main structural, electrical, thermal and optical properties of solid materials, laying the foundation for the study of specific classes of materials used in high-tech devices.
Examination methods: The exam is written (duration 2 h) with an open question and an exercise with numerical applications of the learned topics.
Assessment criteria: The assessment will be based on the comprehension of the proposed topics and on the ability to establish conceptual links between different topics.
Course unit contents: - The crystal structure of solids: the direct lattice and the reciprocal lattice.

- Diffraction of waves by a crystal.

- Elements of lattice dynamics: the classical theory of the harmonic crystal; the specific heat at high temperatures: the law of Dulong-Petit; the normal modes of a monatomic and diatomic linear chain; elementar quantum theory of harmonic crystal; phonons; the distribution of phonons at thermal equilibrium; the concept of density of states; Models of Einstein and Debye for the specific heat of monatomic solids.

- The thermal conductivity in insulating materials.

- The electron gas: The Fermi sphere; total energy and pressure of a gas of electrons at T = 0 K; the heat capacity of an electron gas.

- The electrical conductivity of metals in the Drude model; the thermal conductivity in metals; the Wiedemann-Franz law; the Hall effect in metals: inadequacy of the Drude model; the electron-electron interaction: effects of the screening and the Pauli principle; the dielectric function of the electron gas; Optical properties of the electron gas: plasmons.

- Electronic states in a periodic potential: the Bloch theorem; the nearly-free electron model; the tight-binding electron model; number of allowed electronic states in a band: metals, semimetals/semiconductors and insulators; the effective mass; the holes and their properties.

- Transport properties in solids: the Boltzmann equation; the electrical conductivity in metals; thermoelectric properties.

- Semiconductors: concentration of electrons and holes in intrinsic semiconductors; impurity levels; excitons.
Planned learning activities and teaching methods: Lectures.
