TL;DR: A versatile platform technology based on resonant optical antennas and conductivity patterns for launching and control of propagating graphene plasmons, an essential step for the development of graphene plasmonic circuits.
Journal ArticleDOI
Resolving the electromagnetic mechanism of surface-enhanced light scattering at single hot spots
Pablo Alonso-González,Pablo Albella,Martin Schnell,Jianing Chen,Florian Huth,Aitzol García-Etxarri,Aitzol García-Etxarri,Aitzol García-Etxarri,Fèlix Casanova,Federico Golmar,Libe Arzubiaga,Luis E. Hueso,Javier Aizpurua,Rainer Hillenbrand +13 more
TL;DR: Experimental evidence is provided that the intensity elastically scattered off the object scales with the fourth power of the local field enhancement provided by the antenna, and that the underlying electromagnetic mechanism is identical to the one commonly accepted in surface-enhanced Raman scattering.
Journal ArticleDOI
Appearance of room-temperature ferromagnetism in Cu-doped TiO 2-δ films
S. Duhalde,M F Vignolo,Federico Golmar,C. Chiliotte,C.E. Rodríguez Torres,Leonardo A. Errico,A.F. Cabrera,Mario Rentería,Francisco H. Sánchez,Mariana Weissmann +9 more
TL;DR: In this paper, the magnetic moment of a semiconductor doped with nonmagnetic impurities was calculated from the magnetization curves, and it was shown that the role of oxygen vacancies is crucial for the appearance of ferromagnetism.
Journal ArticleDOI
Experimental Verification of the Spectral Shift between Near- and Far-Field Peak Intensities of Plasmonic Infrared Nanoantennas
Pablo Alonso-González,Pablo Albella,Frank Neubrech,Christian W. Huck,Jianing Chen,Federico Golmar,Fèlix Casanova,Luis E. Hueso,Annemarie Pucci,Javier Aizpurua,Rainer Hillenbrand +10 more
TL;DR: Near-field optical microscopy and far-field spectroscopy of individual infrared-resonant nanoantennas are combined to verify experimentally a distinct spectral shift between the near-and-far- field optical response of plasmonic antennas.
Journal ArticleDOI
Real-space mapping of Fano interference in plasmonic metamolecules.
Pablo Alonso-González,Martin Schnell,Paulo Sarriugarte,Heidar Sobhani,Chihhui Wu,Nihal Arju,Alexander B. Khanikaev,Federico Golmar,Pablo Albella,Libe Arzubiaga,Fèlix Casanova,Luis E. Hueso,Peter Nordlander,Gennady Shvets,Rainer Hillenbrand +14 more
TL;DR: Scattering-type near-field optical microscopy is used to map the spatial field distribution of Fano modes in infrared plasmonic systems, observing in real space the interference of narrow (dark) and broad (bright) plAsmonic resonances.
