Medium dependent optical response in ultra-fine plasmonic nanoparticles

Abstract

We study the influence of media on the interaction of ultra-fine plasmonic nanoparticles ($\leq$8~nm) with radiation. The important role of the surface layer of the nanoparticles, with properties that differ...

Self-powered photodetectors: a device engineering perspective

“…It has been shown that there is spectral tuning with a change in the embedding medium, with air medium showing a peak in the UV region, SiN medium showing a peak in the visible region, and Si medium showing a peak in the infrared region. Sørensen et al 148 studied the effect of the medium on the optical response. It has been found that there is a direct correlation between the refractive index and the amplitude of the plasmon resonance.…”
