Target skills and knowledge: The course aims at providing a rational description of the correlations among structural and microscopic properties of materials, on one hand, and their macroscopic properties (dielectric, optical, magnetic,etc.) on the other hand.
At the end of the course, the student will have acquired skills regarding the tensor nature of the physical properties of the crystals, the dielectric and optical properties of the insulators, the magnetism (dia, para, iron, irons and antiferro magnetism), the optical properties of metals and semiconductors, intermolecular forces, photophysics and molecular photochemistry, non-radiative energy transfer processes, intra- and intermolecular electronic, and molecular electronics elements.
Examination methods: The exam consists of an oral interview that will focus on all the topics covered in class.
We will ask to expose the arguments both in a conceptual way and using mathematical demonstrations and schemes reproduced by the student on the blackboard. Typically, the exam will focus on two topics selected among those treated in class, and you can start from them to make links to other topics.
In case a higher level of knowledge is required of the knowledge acquired by the student, the number of topics covered in the exam will increase.
Assessment criteria: The student should show an acquired understanding of general principles and an ability to apply them for the description of specific material properties and phenomena. Coherent with the interdisciplinary nature of the master degree in Materials Science, he should, to some degree, show the ability to cross boundaries between physics and chemistry and recognize common grounds as well as fictitious or purely semantic differences.

Planned learning activities and teaching methods: The main teaching activities will be delivered as classes. The active participation of students will be fostered and sufficient time will be allotted for questions and answers. Quiz, videos and real samples of materials will be used to this purpose.
From time to time, reference will be made to hot topics in materials science and applied research in order to keep alive the interest of students.
Additional notes about suggested reading: A collection of slides will be available to the students for downloading from the teacher website.
Detailed lesson notes will be available at teacher's home page.
A detailed list of text-books will be provided by the teacher to the students interested at in-depth study.
