Il corso è dedicato a fornire allo studente i fondamenti della fisica e della tecnologia dei moderni dispositivi a semiconduttori (diodi e transitori) nonché dispositivi emergenti e innovativi per l'elaborazione classica e quantistica (convenzionale e non convenzionale) dell’informazione, nonché per applicazioni in neuroelettronica. Oltre alle lezioni frontali, il corso offre due attività di laboratorio dedicate alla caratterizzazione e simulazione (basate su Sentaurus) delle caratteristiche funzionali dei dispositivi.

The
course comprises lectures in the classroom and a laboratory part dedicated to electrical
characterization and simulation.
During the Covid-19 emergency period, the lessons
will take place completely remotely asynchronously with some synchronous
videoconferencing events. For the Labs, if presence is not allowed, we will proceed remotely with mainly simulation activites.

Students
must demonstrate in an interview to know how the main principles of the physics
of semiconductors can be used in the design and development of electronic
devices with specific functions, and how the device functions can be modelled
and analysed in the laboratory with suitable approaches. The oral examination, consists of two, or three questions on different 
parts of the course, where the illustration of the topic is requested to
 be accompanied by sketches, equations and numerical data. The student should choose the first question (topic). 
During the Covid-19 emergency period, oral exams
will only be online. They will be carried out using the WebEx platform and on
the e-learning page of the course there will be a public link for access to the examination of possible virtual spectators.
