The course consists of 35 lectures with students in classroom. A series of lectures may be taken in the Interdepartmental laboratory of electron microscopy (LIME), in order to give students the opportunity to attend some guided experiments using real laboratory equipment, immediately after the related theoretical lecture. Some additional lectures are focused on the direct use by the students of some of the characterization equipment that are available the LIME and the STM labs.Modalità Frequenza
It is highly recommended to follow lectures "in presence", given the practical and experimental nature of this course.Modalità Valutazione
The students will be evaluated by a written and oral examination. It may be possible to have an intermediate examination at the middle of the course.
