Nano-pin plasmonic resonator array and its optical properties
|PDF (1160Kb) |
A one-step electron-beam lithography process for the fabrication of a high-aspect ratio nano-pin array is presented. Each nano-pin is a metal capped dielectric pillar upon a ring shaped metallic disc. Highly tunable optical properties and the electromagnetic interplay between the metallic components were studied by experiment and simulation. The two metallic pieces play asymmetrical roles in their coupling to each other due to their drastic size difference. The structure can lead to ultra-sensitive surface enhanced Raman scattering (SERS) chemical sensor arrays, etc.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
