Learning outcomes and competences

Provide advanced training in nanoscience and nanotechnology that allows students to learn and apply key concepts.

The program includes an introduction to the properties at the nanoscale, followed by learning a set of micro/nanofabrication techniques and technologies including deposition or lithography methodologies. With this part are expected to familiarize themselves with the methodologies on micro / nanofabrication. In the final part will be presented various principles of operation of devices, technologies and / or sensors.

The experiments proposed are realized after the first theoretical/pratical sessions and reading some articles and technical documents provided at the beginning of the course, the students are stimulated to seek additional information to address formation deficiencies. Based on this information students should plan the experiment to be performed. At the end they should prepare a short report on one of the experiments and make an oral presentation.

Teaching methods and learning activities

Theoretical-practical classes (TP)

Presentation of the curriculum using multimedia; specialized topics presented in lectures by invited. The basic principle of the classes will be based on a discussion between students and teachers.

Experimental classes:

The course teaching is based on a problem solving approach. Students, based on knowledge acquired by reading scientific papers and technical documents provided, plan the experiment supported by the teacher. The teachers also support students in the realization of experiment and in its critical analysis. The teacher should also discuss with students what are the most relevant results and those that should be the subject of a more detailed analysis.
