HRTEM and EELS of nanoantenna structures fabricated using focused ion beam techniques

Abstract

This paper describes the use of focused ion beam (FIB) techniques to fabricate Au nanoantenna structures for plasmonics applications. High-resolution transmission electron microscopy (HRTEM), diffraction and electron energy-loss spectroscopy (EELS) techniques are applied to investigate the structures of the initially patterned film, fabricated nanoantenna structures, and to map localized surface plasmon resonance (LSPR) modes in the nanostructures. © 2010 IOP Publishing Ltd.
