Exact polarizability and plasmon resonances of partly buried nanowires.

The electrostatic polarizability for both vertical and horizontal polarization of two conjoined half-cylinders partly buried in a substrate is derived in an analytical closed-form expression. Using the derived analytical polarizabilities we analyze the localized surface plasmon resonances of three important metal nanowire configurations: (1) a half-cylinder, (2) a half-cylinder on a substrate, ...

Polarizability of nanowires at surfaces: exact solution for general geometry.

The polarizability of a nanostructure is an important parameter that determines the optical properties. An exact semi-analytical solution of the electrostatic polarizability of a general geometry consisting of two segments forming a cylinder that can be arbitrarily buried in a substrate is derived using bipolar coordinates, cosine-, and sine-transformations. Based on the presented expressions, ...

Gold Nanowires: Their Synthesis and Surface Plasmon Resonances

The objective of the project was to fabricate gold nano-rods and study the optical properties of gold nano-particles when coupled to Indium Arsenide quantum dots. The gold nano-rods were synthesized by a seed-mediated growth method using CTAB and BDAC as the surfactants, and the feasibility of changing the aspect ratio of the rods and their Plasmon resonance frequency was studied by varying the...

Plasmon resonances of silver nanowires with a nonregular cross section

We investigate numerically the spectrum of plasmon resonances for metallic nanowires with a nonregular cross section, in the 20–50 nm range. We first consider the resonance spectra corresponding to nanowires whose cross sections form different simplexes. The number of resonances strongly increases when the section symmetry decreases: A cylindrical wire exhibits one resonance, whereas we observe...

Plasmon Resonances in Nanowires with a Non-regular Cross-Section

We investigate numerically the spectrum of plasmon resonances for metallic nanowires with a non–regular cross-section in the 20–50 nm range. After briefly recalling the physical properties of metals at optical frequencies, we point out the intrinsic difficulties in the computation of the plasmon resonances for nanoparticles with a non–regular shape. We then consider the resonance spectra corres...
