The third year teaching in the degree course in Materials Science introduces to the basic knowledge of Physics of Solids. Particular importance is given to the ability to interpret the physical properties of solids with the help of appropriate simplifications and mathematical models identifying the validity limits of the model. The program provides an introduction to Crystal structure, electronic structure and vibrational states of Solids.
Intended learning outcomes are
To Acquire basic knowledge of solid state physics in its experimental and theoretical aspects;
To develop a solid working methodology and an interdisciplinary approach to problem solving.
Know how to apply the basic knowledge of classical physics, modern physics and chemistry to the introductory study of Physics of Solids
To be familiar with the mathematical tools necessary to make models useful to describe the behaviour of crystalline solids and to understand its structural, vibrational and electronic properties.
To propose examples of the application of models to solids;
Know how to integrate the knowledge and languages of the various disciplines
Basic knowledge of classical physics, infinitesimal calculus and modern physics
Classroom lessons with examples and applications. The course includes about 64 hours of lectures. Student's participation is required in the discussion that highlights the characteristics of the various models used and their adequacy to interpret the properties of crystalline solids.

The exam consists of an oral exam with two questions on the core concepts of the course (crystal structure, vibrational properties, electronic properties). In addition, the exam is aimed at testing the ability to apply knowledge by making some examples of concrete situations. The talk time is about half an hour. If necessary, a third reserve question is made.
The purpose of the oral exam is to evaluate the degree of achievement of the following learning outcomes: - to know the basic aspects of solid state physics (structure, vibrational properties, electronic properties) - the ability to apply knowledge by making some examples of solid materials; - the ability to use appropriate language and appropriate mathematical tools.
The assessment takes into account all of these elements.
