Surface nano-patterning through styrene adsorption on Si(100)
A. Calzolari, A. Ruini, M. J. Caldas +1
We present an ab initio study of the structural and electronic properties of styrene molecules adsorbed on the dimerized Si(100) surface at different coverages, ranging from the si…
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…
