Main themes The course is divided in three parts. In the first part, the geometric and electronic aspects of clusters and nanowires are studied. Then, we cover carbon nanotubes and associated concepts. Finally, we examine systems for spintronics applications.
Aims In this course, the major concepts relevant for the physics of systems structured at the nanometer level are introduced, and several kinds of such systems are thoroughly investigated : carbon nanotubes ; systems for spintronics applications ; clusters ; nanowires. At the end of their classes, students are expected to be able : 1. To describe the main characteristics and properties of nanometer-structured systems : geometrical aspects, electronic aspects, optical aspects, chemical aspects, transport properties (especially spin transport). 2. To use simple models representing the properties of such systems ; 3. To present numerous applications, and to follow the state-of-the-art concerning the physical properties of nanostructures.
