Objectives The target of this module is an in-depth study of the themes concerning the principles of operation and the design of solid-state semiconductor devices.
One or more analytical models are presented and discussed for each device, together with a SPICE model. Some fundamental techniques for numerical modeling are also discussed.
The competences acquired with this module allow the student to understand how, by means of the carrier generation, recombination, transport in semiconductors it is possible to design devices with given electrical characteristics, such as diodes, transistors, sensors.
Moreover, fundamental concepts are provided concerning the design and fabrication of optoelectronic devices used in modern fibre optic communications systems.
Knowledge and understanding: after passing the exam, the student knows the basic principles of operation of semiconductor electronic devices. He knows the methods to obtain a one-dimensional analytical models of the characteristics of solid-state devices. He knows the techniques for the experimental characterization of these devices.
Ability to apply knowledge: after passing the exam, the student is able to compare the characteristics of devices and identify the one or those most suitable for each application.
Autonomy of judgment: in order to pass the exam, the student must independently answer theoretical, analytical and design questions with free answer and is therefore led to develop an independent judgment on the completeness, depth and correctness of the answers freely provided.
Communication skills: he is able to illustrate the theoretical and technical motivations behind the properties of known devices.
Learning skills: after passing the exam, the student is able to learn independently the basic characteristics of other solid state electronic devices.
