The course is taught in English. Aim of the course (1st semester, 1st year Master’s Degree in Nanotechnologies for ICTs) is to provide the theoretical and the experimental tools concerning materials and characterization techniques involved in micro and nanotechnological processes. The role of this course is central for the development of the professional profile of a nanotechnology engineer, as it develops several skills required for learning the other courses in Master's Degree. The course is divided into two parts: in the first, the student learns the fundamental aspects of the physical and chemical properties of functional materials involved in micro and nanotechnological processes. In the second part, the student learns basic notions about the main characterization techniques dealing with materials (homogeneous and nanostructured) and synthesis processes.

The knowledge transmitted by the course to students involves: - Physical and chemical properties of functional materials involved in micro and nanotechnologies. - Characterization methods devoted to materials, micro/nanostructures and technological processes

- Basic physics (mechanics, thermodynamics, electromagnetism, wave optics, elements of condensed matter physics) - Quantum mechanics. - Elements of statistical mechanics and quantum statistics for fermions and bosons. - Elements of electronics and electrotechnics.
