PHYSICS AND TECHNOLOGY OF ELECTRONIC DEVICES WITH LABORATORY
Solid State Physics and Physics and Semiconductors.
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 course is devoted to provide the student with the fundamentals of the physics and technology of semiconductors devices. In addition to lectures the course offers two laboratory activities dedicated to state of the art electrical characterization and simulation of the devices.
Physics of conventional electronic devices (junctions, transistors), of ultrascaled nanoelectronic devices (single electron and single atom transistors), and of emerging and novel nanoelectronic and spintronic devices for logic and memory applications, and for quantum information processing. Nanoelectronic devices (EOS, EOSFETs, Memristors) for neuroelectronic applications will be also discussed.
