Propriétés optiques des boîtes quantiques de graphène


Graphene quantum dots are new nano-objects made of hundreds of carbon atoms. These atoms can be arranged in various geometries leading to a wide spread of properties. Their intermediate size between small molecules and solids makes them a perfect platform to test theoretical predictions both of quantum chemistry and condensed matter physics. However, accessing this potentialities requires to perform experiments at the single object level.


Recently, our group reported such experiments for the first time [1]. In particular we showed that graphene quantum dots emit single photons at room temperature with a high brightness and good photostability.
