|SCIENTIFIC DISCIPLINARY SECTOR||FIS/03|
You can take the exam for this unit if you passed the following exam(s):
The student will achieve a deep comprehension of the working principles of most common electronic devices, in terms of band structures of semiconductors and heterostructures and transport equations, analysing carrier type and properties. She/he will examine and evaluate physical limitations to a further optimization of device properties as well as technological bottlenecks. She/he will be able to critically evaluate pros and cons of new materials and technologies proposed to continue along the Moore law (More Moore and More than Moore).
Theoretical lectures (48h)
Semiconductors: band structures, electronic properties and transport.
Junctions: Growth and device fabrication – P-n junction and Schottky junction - Band bending at the interface and electronic states – diffusion, generation and recombination – transport – two dimensional electron gases.
Electronic and optoelectronic devices: Diodes – Bipolar Junction Transistors (BJT) – Field effect Transistors (JFET e MOSFET) - CMOS- LED – photodiodes and phototransistors– Photovoltaic cells (hints) - Laser – Quantum cascade lasers.
Developments of electronics and optoelectronics: 2D materials (graphene, Xenes,) – Spintronics

First semester course
Lessons usually start last week of September
Oral exam. The exam is composed by a discussion on an argument chosen by the student (prior agreement with teachers) and by one –two questions on other course’s main topics.
Three days before the discussion, the student must prepare and deliver a short manuscript on the chosen topic.
The oral exam normally lasts between 30 and 40 minutes and questions are chosen to assess the student’s knowledge, her/his ability to think critically and the correct use of scientific language
