BELLANI VITTORIO (titolare) - 6 ECTS

Basic notions of electromagnetism, solid state physics.

Learning of concepts, basic phenomena and applications related to the electrons behaviour and of their spins, in mono- and two dimensional systems and topological materials.

The course describes how we study experimentally the electrons and their spin, in two- and one- dimensional systems and in topological materials. The topics: - Two dimensional nano-structure (quantum wells, superlattices, two dimensional electron gas 2DEG) and one-dimensional (nano-wires). - Study of the quantum behavior of the electrons and of their spin in quantum wells, superlattices and 2DEG using electrical experiments and femto-second laser spectroscopy. - Study of topological states and Majorana Fermions in nanowires using electrical experiments. - Experimental study of the Quantum Hall effect and of the fractional charges using electrical measurements and laser spectroscopy. - Study of the Dirac Fermions and of the electron chirality in graphene and topological material, using electrical experiments and laser spectroscopy in magnetic fields.

Lectures

The most actual bibliography, based on books and scientific papers, will be indicated during the course.

Oral examination with the possibility of a seminar on a topic covered in the course.
