Journal ArticleDOI
Grating-coupling of surface plasmons onto metallic tips : A nanoconfined light source
Claus Ropers,C. C. Neacsu,Thomas Elsaesser,Martin Albrecht,Markus B. Raschke,Christoph Lienau +5 more
TL;DR: A new nanometer-scale broadband light source based on the grating-coupled excitation of surface plasmon polaritons on the shaft of a sharp conical metal taper with a tip radius of few tens of nanometers is described and demonstrated.
Journal ArticleDOI
Exciton binding energies in carbon nanotubes from two-photon photoluminescence
Janina Maultzsch,R. Pomraenke,Stephanie Reich,E. Chang,Deborah Prezzi,Alice Ruini,Elisa Molinari,Michael S. Strano,Christian Thomsen,Christoph Lienau +9 more
TL;DR: In this paper, the binding energies of single-walled carbon nanotubes with diameters between 6.8 and 9.4 were determined by ab initio calculations, based on photoluminescence excitation experiments.
Journal ArticleDOI
Coherent ultrafast charge transfer in an organic photovoltaic blend
S. M. Falke,Carlo Andrea Rozzi,Daniele Brida,Daniele Brida,Margherita Maiuri,Michele Amato,Ephraim Sommer,Antoinietta De Sio,Angel Rubio,Giulio Cerullo,Elisa Molinari,Christoph Lienau +11 more
TL;DR: The results show that coherent vibronic coupling between electronic and nuclear degrees of freedom is of key importance in triggering charge delocalization and transfer in a noncovalently bound reference system.
Journal ArticleDOI
Real-time observation of ultrafast Rabi oscillations between excitons and plasmons in metal nanostructures with J-aggregates
Parinda Vasa,Parinda Vasa,Wei Wang,R. Pomraenke,Melanie Lammers,Margherita Maiuri,Cristian Manzoni,Giulio Cerullo,Christoph Lienau +8 more
TL;DR: In this paper, the authors observed Rabi oscillations in a metal structure with a J-aggregate nonlinear medium and coherent energy transfer between excitonic quantum emitters and surface plasmons.
Journal ArticleDOI
Localized multiphoton emission of femtosecond electron pulses from metal nanotips.
TL;DR: The strong optical nonlinearity of the electron emission allows us to image the local optical field near a metallic nanostructure with a spatial resolution of a few tens of nanometers in a novel tip-enhanced electron emission microscope.
