Learning outcomes

At the end of the course the student has learned foundational concepts of physics of semiconducting materials, nanostructures and devices, with particular focus on material energy band structure, electronic transport and optical properties. The student will be introduced to innovative manufacturing processes of advanced functional materials based on low impact and sustainable deposition/growth methods, like inkjet 2D and 3D printing. This knowledge will be used to address and discuss novel optoelectronic devices of interest in the application fields of energy conversion, radiation detection and light emission.

Teaching methods

The course contents are illustrated and discussed during frontal lectures.

Assessment methods

The exam consists in an oral examination at the end of the course. The oral interview aims at assessing the acquired knowledge related to the topics discussed during the course. The final mark is on a scale 30/30 and the course is passed with a final score equal or greater than 18/30

Teaching tools

The lecture notes of the course will be made available on the website Virtuale of the University of Bologna (virtuale.unibo.it).
