Insegnamento: Laboratory of nanostructures
Physics - Fisica (Offerta formativa 2024)
Obiettivi formativi
The course prepares the students for the experimental research in the physics and technology of nanostructures and nanomaterials.
The course aims at providing the students:
- the knowledge of selected experimental methods and techniques used in in state-of–the-art nanodevice physics and engineering,
- the ability to design, set up and perform the experimental study of devices and materials at the micro and nanoscale,
- the ability to present and discuss, both in written and oral form, the results of an experimental research,
- the ability to search for the relevant literature and exploit it to design the experimental investigation.
Prerequisiti
Knowledge of structure of matter.
Basic knowledge of condensed matter physics.
Knowledge of the basic properties of bulk semiconductors. Mechanisms of radiation-matter interaction.

Risultati attesi
Knowledge and understanding.
At the end of the course the students would know the basic working principle of selected experimental techniques in physics of nanostructures.
Applying knowledge and understanding.
At the end of the course the students would be able to set up and perform experiments to investigate properties of devices and materials at the micro- and nanoscale.
Making judgements.
At the end of the course the student should be able to critically analise the results of their investigation and devise further experiments.
Communicating skills.
At the end of the course students would be able to write clear, rigorous and concise report on experimental activities, to present and discuss orally the results of their investigations in the style of contributed conference talks.
Learning skills.
At the end of the course students would be able to start from research literature to devise their own experimental investigation.
