Prerequisites
Basic concepts of solid state physics (crystal structure, electronic bands, charge carriers, etc) included in the following courses of the Bachelor Degree in Materials Science and Technology:
- "Material characterization methods"
- "Materials for electronics with laboratory"
 
 

Course objectives

- To provide the basic knowledge on the physics of semiconductor devices (carrier statistics, conduction mechanisms, Shockley-Read-Hall theory).

- To provide the basic knowledge of the physics of the most important electronic devices (p-n and Schottky junctions, bipolar junction and field effect transistors, CCD devices).

- To introduce the experimental procedures for the characterization of bipolar junctions and photovoltaic devices.

 

Results of learning outcomes

Knowledge and understanding

  • Understanding the basic concepts on the electrical properties of semiconducting materials and of related devices (bipolar and Schottky junctions, photovoltaic cells, transistors).
  • Understanding of the functionalities of laboratory equipment and of relevant experimental techniques for the characterization of bipolar junctions and photovoltaic devices.

Applying knowledge and understanding

  • Ability to understand and manage fundamental physical models to interpret charge transport mechanisms in semiconductors, as well as the functionalities of main related devices (bipolar and Schottky junctions, photovoltaic cells, transistors).
  • Ability to take experimental measurements, adopting a suitable experimental protocol for the characterization of bipolar junctions and photovoltaic devices
 

Syllabus

- Short review on basic concepts in semiconductor physics

- Tight binding model

- Carrier statistics in intrinsic and extrinsic semiconductors

- Shockley-Read-Hall theory

- Charge transport mechanisms in semiconctors

- p-n junction: derivation of the diode law, non-ideal diode

- Physics and technological aspects of photovoltaic devices

- Metal-semiconductor junction: Schottky diode

- Deep level transient spectroscopy

- Transistors: bipolar junction, JFET, MOSFET

- Charge coupled devices

 

Course delivery

The module is organized in 5 credits (40 hours) of frontal lectures and 1 credit (10 hours) of laboratory activities.

The attendance to the frontal lectures is optional, while it is compulsory (minimum 70% attendance) for the laboratory sessions.

The first 3 credits of frontal lectures will be given in English language. The last 2 credits of frontal lectures will be given either in Italian or English, on the basis of the students' requests and of the presence of foreign students in the class.

The Semiconductor Physics course activated at the Physics Master  Degree and part of the Solid State Physics course activated at the MaMaSELF inter-university Master Degree are mutuated from this module.

 

Learning assessment methods

The partial exam for this module will consist in an oral colloquium of about 30 minutes in which the following aspects will be evaluated:

- understanding of the contents of the frontal lectures, both with regards to the derivation of the formalism presented in the lectures and to the solution of simple numerical problems;

- contents of the reports of the supporting laboratory activities, which the students must produce in groups and deliver at least one week before the exam.

The final mark for this exam results from a joint evaluation of the teachers, on the basis of the marks of the respective partial exams.

 

Support activities

Laboratory activities:

- characterization of a photovoltaic cell;

- charcaterization of a p-n junction at room temperature and at variable temperature.
