A comparative study of solid-silver and silver-shell nanodimers on surface plasmon resonances
Source abstract
Abstract
We investigated numerically the scattering cross sections and near-field intensities of solid-silver and silver-shell (shell thickness d = 10 nm) nanodimers that interact with incident plane wave by the use of finite-element method with three-dimensional models. Results show that the silver-shell cases exhibit tunable surface plasmon resonances and its rotational effects can induce more surface plasmons in a wider range of wavelength that are not observed for the solid-silver cases with the same volume (1,046,666 nm3).
