Today, in “is there something graphene is not capable of“, excitons in graphene. The team lead by professor Paul McEuen (at Cornell University) is studying the optical properties of single-atom-thick layers of graphene. And they have just reported the observation of excitons in a graphene bylayer. These electrically neutral quasiparticles, make graphene of possible interest in the development of optoelectronic devices.

Closely directed by Long Ju, co-lead author of the paper, we made this image to illustrate this finding.
