Contribution of the course to the overall degree programme goals
Expected learning outcomes
i) Knowing and correctly defining the main electrical properties of materials and their classification based on their behavior.
ii) To know which physical phenomena determine their behavior
iii) To know how the phenomenological parameters are connected to the electronic properties of matter
2) Ability to apply knowledge and understanding
i) Knowing how to apply the most appropriate theoretical models for understanding and describing the electrical properties of materials
ii) Knowing which parameters can be used to modify these properties
iii) Know how the materials are selected for different applications
3) Judgment skills
i) Being able to evaluate the logical consistency of the models and the approximations used to describe the electrical properties of the materials.
ii) Knowing how to evaluate the intrinsic limits of the various models.
4) Communication Skills
i) Knowing how to describe the analyzed physical phenomena with an appropriate and scientifically correct language.
ii) Knowing how to justify the application of formalisms also from the mathematical point of view.
iii) Knowing how to interact with the teacher and the classmates by formulating coherent questions
5) Learning Ability
i) Knowing how to take notes also identifying eventual errors or inconsistencies during the lesson (sign errors, copying errors or not appropriately justified formalism changes)
ii) Knowing how to select information based on its relevance.
ii) Knowing how to connect knowledge independently within the course with knowledge deriving from other courses.

It is also suggested a popular scientifically rigorous text that can help to better understand the subject:
"Why Glass is Transparent" by B.S. Chandrasekhar. Publisher: Il Saggiatore unfortunately the Italian edition is out of print but you can find the original version
"Why Things Are the Way They Are" Cambridge University Press, 1998
The oral exam will last between 30-45 minutes and the evaluation will take into account the knowledge of the topics dealt with attention to the following aspects:
- Correct setting of the problem (definition of fundamental quantities, hypothesis and model adopted), the use of the mathematical formalism and knowledge of its physical interpretation.
-The exposure capacity (clarity, linearity and language properties)
The final grade will take into account the results achieved in both the tests of part 1 and 2
In the "Moodle" platform of the University there are all the slides projected during the lessons.
