Disentangling cathodoluminescence spectra in nanophotonics: particle eigenmodes vs transition radiation
Saskia Fiedler, P. Elli Stamatopoulou, Artyom Assadillayev +6
Cathodoluminescence spectroscopy performed in an electron microscope has proven a versatile tool for analysing the near- and far-field optical response of plasmonic and dielectric…
Nonlocal Response of Metallic Nanospheres Probed by Light, Electrons, and Atoms
Thomas Christensen, Wei Yan, Søren Raza +3
Inspired by recent measurements on individual metallic nanospheres that can not be explained with traditional classical electrodynamics, we theoretically investigate the effects of…
Generalized nonlocal optical response in nanoplasmonics
N. Asger Mortensen, Søren Raza, Martijn Wubs +2
Metallic nanostructures exhibit a multitude of optical resonances associated with localized surface plasmon excitations. Recent observations of plasmonic phenomena at the sub-nanom…
Extremely confined gap surface plasmon modes excited by electrons
Søren Raza, Nicolas Stenger, Anders Pors +7
High spatial and energy resolution EELS can be employed for detailed characterization of both localized and propagating surface plasmon excitations supported by metal nanostructure…
Blueshift of the surface plasmon resonance in silver nanoparticles studied with EELS
Søren Raza, Nicolas Stenger, Shima Kadkhodazadeh +6
We study the surface plasmon (SP) resonance energy of isolated spherical Ag nanoparticles dispersed on a silicon nitride substrate in the diameter range 3.5-26 nm with monochromate…
Modified field enhancement in plasmonic nanowire dimers due to nonlocal response
Giuseppe Toscano, Søren Raza, Antti-Pekka Jauho +2
We study the effect of nonlocal optical response on the optical properties of metallic nanowires, by numerically implementing the hydrodynamical Drude model for arbitrary nanowire…
