|SCIENTIFIC DISCIPLINARY SECTOR
The course will introduce in the basic concepts of Surface Science and of the nanostructuring at surfaces handling both theory and experimental methods. Laboratory demonstrations will allow the students to better understand the experimental methods and the basic concepts.
AIMS AND CONTENT
Relevance of surfaces and interfaces in Nanoscience and Nanotechnology. The course will introduce: a) the surface excess quantities and thermodynamical properties of surfaces; b) the surface crystallographic structure with relaxation and reconstruction phenomena; c) the surface electronic ground state properties and the surface states; d) the surface magnetic properties. Specific cases for semiconductor, oxide and insulator surfaces, graphene and other ultrathin films will be discussed with respect to dimensionality with extension towards one and zero dimensions, i.e atomic wires, surface steps and clusters. Excited states at surfaces will be treated: surface phonon spectra, surface electronic and magnetic excitations. Connections to plasmonics, Energy harvesting in solar cells and photoinduced chemistry will be stressed. Gas-Surface interaction, physisorption and chemisorption, dynamics of the interaction, adsorption, desorption, sticking and simple catalytic reactions will be discussed. Crystal growth, MBE, CVD, ablation techniques, nanosized films and clusters will be introduced as well as self-assembled monolayers, artificial nanostructures and surface functionalization. Experimental methods for surface characterization, like Scanning Probe Microscopies and Diffraction Methods, as well as Surface Sensitive Electronic and Vibrational Spectroscopies will be introduced.

in the first semester according to academic calender year
L'orario di tutti gli insegnamenti è consultabile all'indirizzo EasyAcademy.
The students will be examined orally. They will expose a topic of their choice. The commission will then ask to expose a different topic. Questions will be posed by the jury to assess the knowledge level of the student
The students will be examined orally. They will expose a topic of their choice. The commission will then ask to expose a different topic. Questions will be posed by the jury to assess the knowledge level of basic concepts by the student. Sufficiency will be reached when the topics are exposed with proper language and the students demonstrates to have a basic understanding of the concepts assocaited to surface science.
