Surface-Enhanced Plasmon Splitting in a Liquid-Crystal-Coated Gold Nanoparticle
Sung Yong Park, D. Stroud
We show that, when a gold nanoparticle is coated by a thin layer of nematic liquid crystal, the deformation produced by the nanoparticle surface can enhance the splitting of the na…
Splitting of Surface Plasmon Frequencies of Metal Particles in a Nematic Liquid Crystal
Sung Yong Park, D. Stroud
We calculate the effective dielectric function for a suspension of small metallic particles immersed in a nematic liquid crystal (NLC) host. For a random suspension of such particl…
Surface Plasmon Dispersion Relations in Chains of Metallic Nanoparticles: Exact Quasistatic Calculation
Sung Yong Park, David Stroud
We calculate the surface plasmon dispersion relations for a periodic chain of spherical metallic nanoparticles in an isotropic host, including all multipole modes in a generalized…
Structure Formation, Melting, and the Optical Properties of Gold/DNA Nanocomposites: Effects of Relaxation Time
Sung Yong Park, D. Stroud
We present a model for structure formation, melting, and optical properties of gold/DNA nanocomposites. These composites consist of a collection of gold nanoparticles (of radius 50…
Theory of the Optical Properties of a DNA-Modified Gold Nanoparticle System
Sung Yong Park, David Stroud
We describe a simple model for the melting and optical properties of a DNA/gold nanoparticle aggregate. The aggregate is modeled as a cluster of gold nanoparticles on a periodic la…
Theory of Melting and the Optical Properties of Gold/DNA Nanocomposites
Sung Yong Park, D. Stroud
We describe a simple model for the melting and optical properties of a DNA/gold nanoparticle aggregate. The optical properties at fixed wavelength change dramatically at the meltin…
