2. 1. Optical properties of silver nanostructures prepared by electron beam lithography

   Author : Linda K Gunnarsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoelectronics; surface-enhanced Raman spectroscopy; single-electron tunneling; electron-beam lithography; nanofabrication; localized surface plasmon resonance; silver nanoparticles;

   Abstract : In this thesis, electron beam lithography (EBL) has been used to fabricate substrates for studies of nanoparticle optics, in particular for the investigation of noble metal nanoparticles and their tunable optical properties. The strong interaction of metal nanoparticles with light has its origin in the resonant excitation of collective oscillations of conduction electrons, so called localized surface plasmons (LSP).
