    OVERVIEW

    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.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    Intended learning outcomes are 
    To Acquire basic knowledge of solid state physics in its experimental and theoretical aspects;

    EXAMS

    EXAM DESCRIPTION

     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.
    
     

    ASSESSMENT METHODS

    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.
