ELECTRONICS ENGINEERING - Ingegneria Elettronica (D.M.270/04) (Offerta formativa 2020)

Obiettivi formativi

This integrated course addresses the most relevant and innovative electronic and photonic devices and technologies for modern ICT applications

The section on Nanoelectronics focuses on new emerging devices, especially non-volatile memories and their applications. The physical mechanisms and principles of operations at the basis of such emerging devices will be studied in detail. Moreover, the role of these devices in new applications and paradigms will be explored, with a focus on new computational paradigms (advanced neural networks, logic-in-memory, random number generators).

As regards Bioelectronics, the drift-diffusion model for semiconductors is extended to the description of electrolytes and electrolyte/solid interfaces useful to understand the transduction principle of many electronic biosensors. The fundamentals of biosensors (sensitivity, selectivity, response time, noise) are then studied and biosensor concepts are compared to each other.

In particular, the section on Advanced Photonics aims at providing knowledge and design skills-set of the most popular optical and photonics components such as couplers, gratings, interferometers, optical amplifiers, and specialty fibers used both in fiber and integrated photonic technologies.

Prerequisiti

The course has general prerequisites that can be fulfilled by attending the UniMORE Electronic Engineering courses on "Electron devices and components" and "Photonics and Microwaves" (mandatory courses of the first year of the degree in Electronic Engineering @UniMORE) or courses with equivalent general contents.

In particular these contents are:

For the "Electronics" part: essentials of solid state physics, fundamentals of electron devices and of the drift-diffusion modeling framework, as can be found in any Electron Device textbook.

For the "Photonics" part: electromagnetic waves, optical fibers, basics of quantum mechanics, laser.

Metodi didattici

In-class lectures, multimedia tools, tutorials, homeworks, lab activities.

Due to the COVID-19 emergency:

The lectures will be held on line (streaming and recorded).

Laboratory activities may be carried out:
a) remotely via virtualization of laboratory equipment;
b) at home through the use of appropriate kits prepared by the teacher and video tutorial showing the activity.

Simulation activities will be based on the www.nanohub.org portal.

Work group activities will be held on-line by using proper software platforms.
