Background on solid state physics is recommended
The course deals with the working principle of the most important electronic devices (diodes, bipolar junction transistor, CMOS technology ...) and photonic devices (LED, Laser, optical fibers, photovoltaic devices ...).
It is organized in the following parts:
- Introduction on the solid state physics, energy bands and current transport mechanisms in semiconductors.
- Two terminal and three terminal electronic devices (p-n and Schottky junction diodes, bipolar transistors and MOSFETs
- light emitting and detecting photonic devices
The course also includes lectures on simulation of devices behavior.
Knowledge and understanding. Students must have a background in electromagnetic fields and waves and basic background in material science:
- the students must have the basic cognitive tools to understand semiconductor crystals and their electronic properties and apply this to understand how electrons move and distribute in a semiconductor device;
- they must have a solid knowledge of the electromagnetic waves and fields;
- they must be able to understand electric fields, potentials and voltages and electrostatic properties of materials;
- They must have a basic knowledge of electronic circuits, passive and active two- and three-terminals electronic devices.
Applying knowledge and understanding. After the course the student should be able to:
- understand what are the carrier transport, absorption and recombination mechanisms in semiconductor devices;
- understand how an electronic device works and what are the key parameters to design an efficient two terminal or three terminal electronic devices;
- design a LED or Laser device for different photonic applications;
- understand and design a photodetector.
Making judgements. Students are guided to learn critically everything that is explained to them in class, to understand the behavior of the state of the art technologies for electronic and photonic devices and to design new devices.
Communication. The students will be stimulated to be able to communicate with a varied and composite audience, not culturally homogeneous, in a clear, logical and effective way, using the methodological tools acquired and their scientific knowledge and, in particular, with and professional and scientific vocabulary.
Learning skills. Students must acquire the critical ability to understand the behavior of devices at the nanoscale. They should be able to develop and apply independently the knowledge and methods learnt with a view to possible continuation of studies at higher (doctoral) level or in the broader perspective of cultural and professional self-improvement of lifelong learning.
The teaching of the course will make use of both the blackboard and projection of videos and slides. Simulation of devices will be also done by exploiting freely available online tools.
Oral exam. The student is asked theoretical questions on each part of the course. During the discussion the student is asked to elaborate on the purpose of specific technological solutions in the design and fabrication of electronic devices and he/she is also asked to propose a different solution for a device with specific properties.
