dc.description.abstract |
This study involves two aspects of our investigations of plasmonics-active systems:
(i) theoretical and simulation studies and (ii) experimental fabrication of plasmonics-active
nanostructures. Two types of nanostructures are selected as the model systems for
their unique plasmonics properties: (1) nanoparticles and (2) nanowires on substrate.
Special focus is devoted to regions where the electromagnetic field is strongly concentrated
by the metallic nanostructures or between nanostructures. The theoretical investigations
deal with dimers of nanoparticles and nanoshells using a semi-analytical method based
on a multipole expansion (ME) and the finite-element method (FEM) in order to determine
the electromagnetic enhancement, especially at the interface areas of two adjacent
nanoparticles. The experimental study involves the design of plasmonics-active nanowire
arrays on substrates that can provide efficient electromagnetic enhancement in regions
around and between the nanostructures. Fabrication of these nanowire structures over
large chip-scale areas (from a few millimeters to a few centimeters) as well as FDTD
simulations to estimate the EM fields between the nanowires are described. The application
of these nanowire chips using surface-enhanced Raman scattering (SERS) for detection
of chemicals and labeled DNA molecules is described to illustrate the potential of
the plasmonics chips for sensing.
