Article Synopsis
- The study highlights that traditional light scattering analysis of plasmonic nanoparticles doesn't account for the finite thickness of real interfaces, which leads to unique surface effects due to quantum electron behavior.
- By using electrical gating, the research investigates how charging single plasmonic nanoresonators affects light scattering, revealing that both resonance shifts and changes in resonance width can happen.
- The findings suggest that these nonclassical surface responses could have significant applications in creating electrically controlled plasmonic devices and metasurfaces.
Visible and infrared photons can be detected with a broadband response via the internal photoeffect. By use of plasmonic nanostructures, i.e.

In this context, exciting plasmons with a distinct modal field profile constitutes a key advantage over conventional single-mode integrated photonics. Here, we demonstrate the selective electrical excitation of the lowest-order symmetric and antisymmetric plasmonic modes in a two-wire transmission line.

We recorded diffraction patterns using a commercially available slit and sensor over a wide range of experimental circumstances, including near- and far-field regimes and oblique incidence at large angles. We then compared the measured patterns with theoretical intensity curves calculated via the numerical integration of formulas derived within the framework of scalar diffraction theory. Experiment and theory show particularly good agreement when the first Rayleigh-Sommerfeld (R-S) formula is used.
