Design of Plasmonic Nanostructures for Improving the Detection in Raman Spectroscopy, Ph.D. Dissertation Sharif University of Technology ; Rashidian, Bizhan (Supervisor) ; Shahmansouri, Afsaneh (Co-Advisor)
Abstract
Excitation of Localized Surface Plasmons, which is one of the features of the metal nanostructures, results in the confinement of light in the dimensions smaller than the incidence wavelength, and even lower than the fundamental diffraction limit. This property causes electric field enhancement at surface, helping the occurrence of Surface Enhanced Raman Scattering (SERS). The amount of electric field enhancement and its resonance frequency depend on the type of material, its geometrical properties and its shape, and the arrangement of the scattering particles. Also, properties of surrounding environment material and the type of the excited mode of the structure, and the incidence wave...
