## PHYSICS OF SOLIDS

CODE 61496 2020/2021 8 credits during the 3nd year of 8765 Material Science (L-30) GENOVA FIS/03 Italian GENOVA (Material Science) 1° Semester AULAWEB

## 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

## EXAMS

### EXAM DESCRIPTION

` The exam consists of an oral exam with two questions on the core concepts of the course, and the possibility to apply them to concrete situations. The talk time is about half an hour. If necessary, a third reserve question is made.`
`For students attending, the first subject is chosen by the student. The second topic is proposed by the examination board.`

### ASSESSMENT METHODS

`The purpose of the oral exam is to determine the degree to which the following learning outcomes are achieved: to know the basic aspects of solid state physics, ability to apply them, ability to use a specific language and appropriate mathematical tools.`
`The assessment takes into account all of these elements.`
