  • Analysis of poration-induced changes in cells from laser-activated plasmonic substrates 
    Saklayen, Nabiha; Kalies, Stefan; Madrid, Marinna; Nuzzo, Valeria; Huber, Marinus; Shen, Weilu; Sinanan-Singh, Jasmine; Heinemann, Dag; Heisterkamp, Alexander; Mazur, Eric (Washington, DC : Optical Society of America, 2017)
    Laser-exposed plasmonic substrates permeabilize the plasma membrane of cells when in close contact to deliver cell-impermeable cargo. While studies have determined the cargo delivery efficiency and viability of laser-exposed ...
  • Anisotropic dispersion and partial localization of acoustic surface plasmons on an atomically stepped surface: Au(788) 
    Smerieri, M.; Vattuone, L.; Savio, L.; Langer, Thomas; Tegenkamp, Christoph; Pfnür, Herbert; Silkin, V.M.; Rocca, M. (College Park, MD : American Physical Society, 2014)
    Understanding acoustic surface plasmons (ASPs) in the presence of nanosized gratings is necessary for the development of future devices that couple light with ASPs. We show here by experiment and theory that two ASPs exist ...
  • Correlated motion of electrons on the Au(111) surface: Anomalous acoustic surface-plasmon dispersion and single-particle excitations 
    Vattuone, L.; Smerieri, M.; Langer, Thomas; Tegenkamp, Christoph; Pfnür, Herbert; Silkin, V.M.; Chulkov, E.V.; Echenique, P.M.; Rocca, M. (College Park, MD : American Physical Society, 2013)
    The linear dispersion of the low-dimensional acoustic surface plasmon (ASP) opens perspectives in energy conversion, transport, and confinement far below optical frequencies. Although the ASP exists in a wide class of ...
  • Giant photogalvanic effect in noncentrosymmetric plasmonic nanoparticles 
    Zhukovsky, Sergei V.; Babicheva, Viktoriia E.; Evlyukhin, Andrey B.; Protsenko, Igor E.; Lavrinenko, Andrei V.; Uskov, Alexander V. (College Park, MD : American Physical Society, 2014)
    Photoelectric properties of noncentrosymmetric, similarly oriented metallic nanoparticles embedded in a homogeneous semiconductor matrix are theoretically studied. Because of the asymmetric shape of the nanoparticle boundary, ...
  • Investigating the origin of third harmonic generation from diabolo optical antennas 
    Shi, Liping; Andrade, Jose R.C.; Kim, Hyunwoong; Han, Seunghwoi; Nicolas, Rana; Franz, Dominik; Boutu, Willem; Heidenblut, Torsten; Segerink, Frans B.; Bastiaens, Bert; Merdji, Hamed; Kim, Seung-Woo; Morgner, Uwe; Kovačev, Milutin (American Institute of Physics Inc., 2017)
    We propose to use diabolo nanoantennas for experimentally investigating the origin of the enhanced third harmonic generation by localized surface plasmon polaritons. In such a geometry, the opposing apexes of bowties are ...
  • Mechanistic insights into plasmonic photocatalysts in utilizing visible light 
    Leong, Kah Hon; Aziz, Azrina Abd; Sim, Lan Ching; Saravanan, Pichiah; Jang, Min; Bahnemann, Detlef W. (Frankfurt am Main : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2018)
    The utilisation of sunlight as an abundant and renewable resource has motivated the development of sustainable photocatalysts that can collectively harvest visible light. However, the bottleneck in utilising the low energy ...
  • New insights into the surface plasmon resonance (SPR) driven photocatalytic H2 production of Au-TiO2 
    Nie, Jinlin; Schneider, Jenny; Sieland, Fabian; Zhou, Long; Xia, Shuwei; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2018)
    The Surface Plasmon Resonance (SPR) driven photocatalytic H2 production upon visible light illumination (≥500 nm) was investigated on gold-loaded TiO2 (Au-TiO2). It has been clearly shown that the Au-SPR can directly lead ...
  • Optical transparency by detuned electrical dipoles 
    Bozhevolnyi, Sergey I.; Evlyukhin, Andrey B.; Pors, Anders; Nielsen, Michael G.; Willatzen, Morten; Albrektsen, Ole (Bristol : IOP Publishing Ltd., 2011)
    We demonstrate that optical transparency can be realized with plasmonic metamaterials using unit cells consisting of detuned electrical dipoles (DED), thereby mimicking the dressed-state picture of the electromagnetically ...
  • Sheet plasmons in modulated graphene on Ir(111) 
    Langer, Thomas; Förster, D.F.; Busse, C.; Michely, T.; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2011)
    The sheet plasmon of graphene on Ir(111) was investigated in this paper by means of high-resolution electron energy loss spectroscopy. The perfect lateral coordination of sp2-hybridized C atoms on a large scale is manifested ...
  • Surface plasmons on ordered and bi-continuous spongy nanoporous gold 
    Sardana, Neha; Birr, Tobias; Schlenker, Sven; Reinhardt, Carsten; Schilling, Jörg (Bristol : IOP Publishing Ltd., 2014)
    The dispersion relation and propagation of surface plasmons polaritons (SPPs) on nanoporous gold films is experimentally investigated and an increasing red shift of the SPPs is observed with rising porosity. This is caused ...
