Understanding the fundamentals of surface science and the physical and chemical properties of surfaces and of nanosized objects grown at surfaces..
Relevance of surfaces and interfaces in Nanoscience and Nanotechnology. Surface excess quantities and thermodynamical properties of surfaces. Crystallographic structure: relaxation and reconstruction. Electronic ground state properties of metals and surface states. Surface magnetism. Specific cases for semiconductor, oxide and insulator surfaces, graphene and other ultrathin films. Towards one and zero dimensions, atomic wires and clusters at surfaces. Excited states at surfaces: surface phonon spectra, surface electronic and magnetic excitations. Connections to plasmonics, Energy harvesting in solar cells and photoinduced chemistry. Gas-Surface interaction, physisorption and chemisorption, dynamics of the interaction, asdsoprtion, desorption, sticking and simple catalytic reactions. Crystal growth, MBE, CVD, Ablation techniques, Nanosized films and clusters. Self-assembled monolayers and artificial nanostructures. Experimental methods for surface science: Scanning Probe Microscopies, Surface Sensitive Spectroscopies and Diffraction Methods.
