Conoscenze

Gli studenti acquisiranno conoscenze sulla teoria, sui modelli e sul progetto di strutture e di  dispositivi a semiconduttore di ultima generazione (ad esempio in scala submicrometrica e nanometrica) utilizzando la meccanica quantistica di base. Saranno discusse risoluzioni analitiche e numeriche di semplici casi di studio.

 

Knowledge

Students are expected to acquire knowledge about theory, models and design of last generation semiconductor device structures , (e.g. at the submicrometric and nanometric scale) using basic quantum mechanics. Analytical and numerical resolutions of simple study cases will be discussed.

Indicazioni metodologiche

Il corso viene tenuto in italiano utilizzando slide che oono messe a disposizione dello studente tramite il sito e-learning. Le slide sono commentate e integrate con calcoli e precisazioni scritte a mano. Gli studenti possono usufruire del ricevimento e dell'indirizzo di posta elettronica dei docenti per chiarimenti tematici e organizzativi.

Teaching methods

The class is taught in Italian, using slides that are made available to the students via the e-learning web site. The slides are presented and integrated with handwritten calculations and comments. Students can obtain clarifications on specific topics and on organizational aspects during the instructors' office hours and contacting the instructors by e-mail.
