Two dimensional materials have been brought in solid state laboratories about 10 years ago and they display fascinating electronic and optical properties. They are foreseen in a large number of potential applications taking advantage of their flexibility, their mechanical robustness and of the large variety of their electronic properties (semiconductors, superconductors, insulators, …) . Optical techniques, combined with low temperature and possibly high magnetic fields environments, are extremely well adapted tools to study these materials as they are non-invasive and contactless. In this lecture, I will describe how transmission/reflection, photoluminescence and light scattering experiments can reveal the very exotic behavior of charge carriers confined within these purely two-dimensional systems.


Clément Faugeras received in 2000 an engineering degree and a PhD in 2003 from the University of Grenoble. He then joined University Paris 7 as a postdoctoral fellow where he worked on infrared sources, the quantum cascade lasers. Since 2006, he is a staff member of the Grenoble High Magnetic Field Laboratory where he develops an activity of optical spectroscopy of semiconductor nanostructures and of two dimensional materials in extreme environments, namely low temperatures and high magnetic fields.
