The course will give an account on the theoretical and experimental aspects of this approach providing unique access to electronic properties at the nanoscale. Whenever required, notions of thermodynamics, electronic theory and crystallography of surfaces will be introduced from scratch. More classical methods, will sometimes be introduced as the basic premises to the presentation of local probe techniques.
The lecture will be illustrated by numerous examples of the scientific literature and should enable a glimpse at the fascinating challenges in the field of the nanosciences. Opportunities will be given to describe the complex mechanisms that are at the origin of the growth of nano-objects on surfaces by self-organization. These include understanding the stability of
aggregates by means of simple atomistic models. Finally, making use of the spectroscopic ability of local probes, we will describe how to access magnetic, optical and superconducting
properties of molecules, clusters and nanoparticles on surfaces. Special attention will be devoted to the interaction of these objects with their environment.
