Nanoplasmonic surfaces enabling strong surface-normal electric field enhancement.
Conventional two-dimensional (2D) plasmonic arrays provide electric field intensity enhancement in the plane, typically with a surface coverage around 50% in the plan-view. Here, we show nanoplasmonic three-dimensional (3D) surfaces with 100% surface coverage enabling strong surface-normal field enhancement. Experimental measurements are found to agree well with the full electromagnetic solutio...
متن کاملNanoparticle Near-Surface Electric Field.
Theoretical studies show that surface reconstruction in some crystals involves splitting the surface atomic layer into two-upper and lower-sublayers consisting of atoms with only positive or only negative effective electric charges, respectively. In a macroscopic crystal with an almost infinite surface, the electric field induced by such a surface-dipole is practically totally concentrated betw...

متن کاملAdditional Enhancement of Electric Field in Surface-Enhanced Raman Scattering due to Fresnel Mechanism
Surface-enhanced Raman scattering (SERS) is attracting increasing interest for chemical sensing, surface science research and as an intriguing challenge in nanoscale plasmonic engineering. Several studies have shown that SERS intensities are increased when metal island film substrates are excited through a transparent base material, rather than directly through air. However, to our knowledge, t...
متن کاملSurface Electric Field of Bare Strange Stars
The surface electric characteristics of bare strange stars are investigated with the inclusion of the boundary effect. The thickness of the electron layer where pairs can be spontaneously created is calculated as a function of the bag parameters. We find that previous estimates are representative for bag parameters within rather wide range, and therefore our results favor the thermal radiation ...
