Splitting of the Al surface plasmon dispersion curves by Ag surface layers
نویسندگان
چکیده
2014 The effects of very thin Ag surface layers on the propagation of surface plasma waves (S.P.W.) excited by ATR at an Al surface are investigated in the vicinity of the Ag plasma frequency and the S.P.W. dispersion relations, are obtained. A splitting of the dispersion curves is found for Ag layers 26, 39 and 58 Å thick, but does not appear for thinner layers. Experimental and computed dispersion curves are compared.

The influence of plasma waves on the dispersion of surface plasmons : experimental evidence
2014 Surface plasmon excitation by attenuated total reflection in Otto geometry has been carried out in a wide spectral range between 1.9 and 5 eV. Samples were Al-films covered by thin (5 nm) continuous Ag-layers. Results were discussed in the framework of a hydrodynamic model of the conduction electrons both in the film and in the substrate using additional boundary conditions. The calculated...
متن کاملTunable Dipole Surface Plasmon Resonances of Silver Nanoparticles by Cladding Dielectric Layers
The tunability of surface plasmon resonance can enable the highest degree of localised surface plasmon enhancement to be achieved, based on the emitting or absorbing wavelength. In this article, tunable dipole surface plasmon resonances of Ag nanoparticles (NPs) are realized by modification of the SiO2 dielectric layer thicknesses. SiO2 layers both beneath and over the Ag NPs affected the reson...
متن کاملSurface plasmon resonance properties of silver nanoparticle 2D sheets on metal gratings
Grating-coupled propagating surface plasmons associated with silver-nanoparticle 2D crystalline sheets exhibit sensitive plasmonic resonance tuning. Multilayered silver-nanoparticle 2D crystalline sheets are fabricated on gold or silver grating surfaces by the Langmuir- Blodgett method. We show that the deposition of Ag crystalline nanosheets on Au or Ag grating surfaces causes a drastic change...
متن کاملInvestigation of metallic surface layers on metals by surface plasmon ATR spectroscopy
2014 The optical properties of very thin Ag layers on Al surfaces were investigated in the vicinity of the Ag effective plasma frequency, by attenuated total reflection with surface plasma wave excitation. The complex dielectric constant of the adsorbed layers is found to be similar to that of bulk Ag provided non-local effects (longitudinal plasma waves) are taken into account. LE JOURNAL DE P...
متن کاملPlanar metal plasmon waveguides: frequency-dependent dispersion, propagation, localization, and loss beyond the free electron model
A numerical analysis of surface plasmon dispersion, propagation, and localization on smooth lossy films is presented. Particular attention is given to determining wavelength-dependent behavior of thin Ag slab waveguides embedded in a symmetric SiO2 environment. Rather than considering Ag as a damped free electron gas, the metal is defined by the experimentally determined optical constants of Jo...
