Optical properties of graphene nanoribbons: the role of many-body effects
D. Prezzi, D. Varsano, A. Ruini +2
We investigate from first principles the optoelectronic properties of nanometer-sized armchair graphene nanoribbons (GNRs). We show that many-body effects are essential to correctl…

Exciton binding energies in carbon nanotubes from two-photon photoluminescence
J. Maultzsch, R. Pomraenke, S. Reich +7
One- and two-photon luminescence excitation spectroscopy showed a series of distinct excitonic states in single-walled carbon nanotubes. The energy splitting between one- and two-p…
