Fundamentals of Crystal growth; definition of phase transitions; Nucleation; Thermodynamic and kinetic aspects.

Flowdynamic in Crystal grwoth from the melt; concept of boundary layer; segregation phenomena; distribution of impurities within crystals and layers.

Growth techniques for bulk crystals (from the melt, solution, vapour).

Thin films growth; (molecular beam epitaxy, liquid phase epitaxy, vapour phase epitaxy, sputtering, laser ablation.

Mismatch between films and substrates; strained heterostructures and relaxation.

Formation of extended and point defects; classification of defects and strategies for lowering the defect density; "useful" defects.

Teaching methods

Lectures in classroom supported by audio-visual media.
Possibility of streaming in case of students who will not be able to attend lectures.

Assessment methods and criteria

Oral exam including:

- Short seminar (max 20 min) on a topic chosen among those presented in the course

- Questions on course's content in order to check how familiar the student is with topics and basic concepts.

Final mark will be based for 1/3 on the seminar and 2/3 on the question time.

Should the evolution of sanitary situation impede the oral examination in presence, the exams will take place in remote, however method and evaluation of students will not change

Other information
